-* API and CLI interfaces are split, so API stays in this repository while CLI moves to [clean-css-cli](https://github.com/clean-css/clean-css-cli);
+clean-css 4.2 introduces the following changes / features:
-* `root`, `relativeTo`, and `target` options are replaced by a single `rebaseTo` option - this means that rebasing URLs and import inlining is much simpler but may not be (YMMV) as powerful as in 3.x;
+
-* `debug` option is gone as stats are always provided in output object under `stats` property;
-* `roundingPrecision` is disabled by default;
-* `roundingPrecision` applies to **all** units now, not only `px` as in 3.x;
-* `processImport` and `processImportFrom` are merged into `inline` option which defaults to `local`. Remote `@import` rules are **NOT** inlined by default anymore;
-* splits `inliner: { request: ..., timeout: ... }` option into `inlineRequest` and `inlineTimeout` options;

-If clean-css encounters invalid CSS, it will try to remove the invalid part and continue optimizing the rest of the code. It will make you aware of the problem by generating an error or warning.

-// Each key in this object represents a CSS property and should be an object.

-// Possible options:
-//
-// * components: array (Only specify for shorthand properties.)
-//   Contains the names of the granular properties this shorthand compacts.
-//
-// * canOverride: function
-//   Returns whether two tokens of this property can be merged with each other.
-//   This property has no meaning for shorthands.
-//
-// * defaultValue: string
-//   Specifies the default value of the property according to the CSS standard.
-//   For shorthand, this is used when every component is set to its default value, therefore it should be the shortest possible default value of all the components.
-//
-// * shortestValue: string
-//   Specifies the shortest possible value the property can possibly have.
-//   (Falls back to defaultValue if unspecified.)
-//
-// * breakUp: function (Only specify for shorthand properties.)
-//   Breaks the shorthand up to its components.
-//
-// * restore: function (Only specify for shorthand properties.)
-//   Puts the shorthand together from its components.

-# Node.js version support
-
-clean-css requires Node.js 4.0+ (tested on Linux, OS X, and Windows)
-
-# Install
-
-```
-npm install --save-dev clean-css
-```
-
-# Use
-
-```js
-var CleanCSS = require('clean-css');
-var input = 'a{font-weight:bold;}';
-var options = { /* options */ };
-var output = new CleanCSS(options).minify(input);
-```
-
-## Important: 4.0 breaking changes
-
-clean-css 4.0 introduces some breaking changes:
-
-* API and CLI interfaces are split, so API stays in this repository while CLI moves to [clean-css-cli](https://github.com/jakubpawlowicz/clean-css-cli);
-* `root`, `relativeTo`, and `target` options are replaced by a single `rebaseTo` option - this means that rebasing URLs and import inlining is much simpler but may not be (YMMV) as powerful as in 3.x;
-* `debug` option is gone as stats are always provided in output object under `stats` property;
-* `roundingPrecision` is disabled by default;
-* `roundingPrecision` applies to **all** units now, not only `px` as in 3.x;
-* `processImport` and `processImportFrom` are merged into `inline` option which defaults to `local`. Remote `@import` rules are **NOT** inlined by default anymore;
-* splits `inliner: { request: ..., timeout: ... }` option into `inlineRequest` and `inlineTimeout` options;
-* remote resources without a protocol, e.g. `//fonts.googleapis.com/css?family=Domine:700`, are not inlined anymore;
-* changes default Internet Explorer compatibility from 9+ to 10+, to revert the old default use `{ compatibility: 'ie9' }` flag;
-* renames `keepSpecialComments` to `specialComments`;
-* moves `roundingPrecision` and `specialComments` to level 1 optimizations options, see examples;
-* moves `mediaMerging`, `restructuring`, `semanticMerging`, and `shorthandCompacting` to level 2 optimizations options, see examples below;
-* renames `shorthandCompacting` option to `mergeIntoShorthands`;
-* level 1 optimizations are the new default, up to 3.x it was level 2;
-* `keepBreaks` option is replaced with `{ format: 'keep-breaks' }` to ease transition;
-* `sourceMap` option has to be a boolean from now on - to specify an input source map pass it a 2nd argument to `minify` method or via a hash instead;
-* `aggressiveMerging` option is removed as aggressive merging is replaced by smarter override merging.
-
-## What's new in version 4.1
-
-clean-css 4.1 introduces the following changes / features:
-
-* `inline: false` as an alias to `inline: ['none']`;
-* `multiplePseudoMerging` compatibility flag controlling merging of rules with multiple pseudo classes / elements;
-* `removeEmpty` flag in level 1 optimizations controlling removal of rules and nested blocks;
-* `removeEmpty` flag in level 2 optimizations controlling removal of rules and nested blocks;
-* `compatibility: { selectors: { mergeLimit: <number> } }` flag in compatibility settings controlling maximum number of selectors in a single rule;
-* `minify` method improved signature accepting a list of hashes for a predictable traversal;
-* `selectorsSortingMethod` level 1 optimization allows `false` or `'none'` for disabling selector sorting;
-* `fetch` option controlling a function for handling remote requests;
-* new `font` shorthand and `font-*` longhand optimizers;
-* removal of `optimizeFont` flag in level 1 optimizations due to new `font` shorthand optimizer;
-* `skipProperties` flag in level 2 optimizations controlling which properties won't be optimized;
-* new `animation` shorthand and `animation-*` longhand optimizers;
-* `removeUnusedAtRules` level 2 optimization controlling removal of unused `@counter-style`, `@font-face`, `@keyframes`, and `@namespace` at rules;
-* the [web interface](https://jakubpawlowicz.github.io/clean-css) gets an improved settings panel with "reset to defaults", instant option changes, and settings being persisted across sessions.
-
-## What's new in version 4.2
-
-clean-css 4.2 introduces the following changes / features:
-
-* Adds `process` method for compatibility with optimize-css-assets-webpack-plugin;
-* new `transition` property optimizer;
-* preserves any CSS content between `/* clean-css ignore:start */` and `/* clean-css ignore:end */` comments;
-* allows filtering based on selector in `transform` callback, see [example](#how-to-apply-arbitrary-transformations-to-css-properties);
-* adds configurable line breaks via `format: { breakWith: 'lf' }` option.
-
-## Constructor options
-
-clean-css constructor accepts a hash as a parameter with the following options available:
-
-* `compatibility` - controls compatibility mode used; defaults to `ie10+`; see [compatibility modes](#compatibility-modes) for examples;
-* `fetch` - controls a function for handling remote requests; see [fetch option](#fetch-option) for examples (since 4.1.0);
-* `format` - controls output CSS formatting; defaults to `false`; see [formatting options](#formatting-options) for examples;
-* `inline` - controls `@import` inlining rules; defaults to `'local'`; see [inlining options](#inlining-options) for examples;
-* `inlineRequest` - controls extra options for inlining remote `@import` rules, can be any of [HTTP(S) request options](https://nodejs.org/api/http.html#http_http_request_options_callback);
-* `inlineTimeout` - controls number of milliseconds after which inlining a remote `@import` fails; defaults to 5000;
-* `level` - controls optimization level used; defaults to `1`; see [optimization levels](#optimization-levels) for examples;
-* `rebase` - controls URL rebasing; defaults to `true`;
-* `rebaseTo` - controls a directory to which all URLs are rebased, most likely the directory under which the output file will live; defaults to the current directory;
-* `returnPromise` - controls whether `minify` method returns a Promise object or not; defaults to `false`; see [promise interface](#promise-interface) for examples;
-* `sourceMap` - controls whether an output source map is built; defaults to `false`;
-* `sourceMapInlineSources` - controls embedding sources inside a source map's `sourcesContent` field; defaults to false.
-
-## Compatibility modes
-
-There is a certain number of compatibility mode shortcuts, namely:
-
-* `new CleanCSS({ compatibility: '*' })` (default) - Internet Explorer 10+ compatibility mode
-* `new CleanCSS({ compatibility: 'ie9' })` - Internet Explorer 9+ compatibility mode
-* `new CleanCSS({ compatibility: 'ie8' })` - Internet Explorer 8+ compatibility mode
-* `new CleanCSS({ compatibility: 'ie7' })` - Internet Explorer 7+ compatibility mode

-You can also use a string when setting a compatibility mode, e.g.
-
-```js
-new CleanCSS({
-  compatibility: 'ie9,-properties.merging' // sets compatibility to IE9 mode with disabled property merging
-})
-```
-
-## Fetch option
-
-The `fetch` option accepts a function which handles remote resource fetching, e.g.
-
-```js
-var request = require('request');
-var source = '@import url(http://example.com/path/to/stylesheet.css);';
-new CleanCSS({
-  fetch: function (uri, inlineRequest, inlineTimeout, callback) {
-    request(uri, function (error, response, body) {
-      if (error) {
-        callback(error, null);
-      } else if (response && response.statusCode != 200) {
-        callback(response.statusCode, null);
-      } else {
-        callback(null, body);
-      }
-    });
-  }
-}).minify(source);
-```
-
-This option provides a convenient way of overriding the default fetching logic if it doesn't support a particular feature, say CONNECT proxies.
-
-Unless given, the default [loadRemoteResource](https://github.com/jakubpawlowicz/clean-css/blob/master/lib/reader/load-remote-resource.js) logic is used.
-
-## Formatting options
-
-By default output CSS is formatted without any whitespace unless a `format` option is given.
-First of all there are two shorthands:
-
-```js
-new CleanCSS({
-  format: 'beautify' // formats output in a really nice way
-})
-```
-
-and
-
-```js
-new CleanCSS({
-  format: 'keep-breaks' // formats output the default way but adds line breaks for improved readability
-})
-```
-
-however `format` option also accept a fine-grained set of options:
-
-```js
-new CleanCSS({
-  format: {
-    breaks: { // controls where to insert breaks
-      afterAtRule: false, // controls if a line break comes after an at-rule; e.g. `@charset`; defaults to `false`
-      afterBlockBegins: false, // controls if a line break comes after a block begins; e.g. `@media`; defaults to `false`
-      afterBlockEnds: false, // controls if a line break comes after a block ends, defaults to `false`
-      afterComment: false, // controls if a line break comes after a comment; defaults to `false`
-      afterProperty: false, // controls if a line break comes after a property; defaults to `false`
-      afterRuleBegins: false, // controls if a line break comes after a rule begins; defaults to `false`
-      afterRuleEnds: false, // controls if a line break comes after a rule ends; defaults to `false`
-      beforeBlockEnds: false, // controls if a line break comes before a block ends; defaults to `false`
-      betweenSelectors: false // controls if a line break comes between selectors; defaults to `false`
-    },
-    breakWith: '\n', // controls the new line character, can be `'\r\n'` or `'\n'` (aliased as `'windows'` and `'unix'` or `'crlf'` and `'lf'`); defaults to system one, so former on Windows and latter on Unix
-    indentBy: 0, // controls number of characters to indent with; defaults to `0`
-    indentWith: 'space', // controls a character to indent with, can be `'space'` or `'tab'`; defaults to `'space'`
-    spaces: { // controls where to insert spaces
-      aroundSelectorRelation: false, // controls if spaces come around selector relations; e.g. `div > a`; defaults to `false`
-      beforeBlockBegins: false, // controls if a space comes before a block begins; e.g. `.block {`; defaults to `false`
-      beforeValue: false // controls if a space comes before a value; e.g. `width: 1rem`; defaults to `false`
-    },
-    wrapAt: false // controls maximum line length; defaults to `false`
-  }
-})
-```
-
-## Inlining options
-
-`inline` option whitelists which `@import` rules will be processed, e.g.
-
-```js
-new CleanCSS({
-  inline: ['local'] // default; enables local inlining only
-})
-```
-
-```js
-new CleanCSS({
-  inline: ['none'] // disables all inlining
-})
-```
-
-```js
-// introduced in clean-css 4.1.0
-
-new CleanCSS({
-  inline: false // disables all inlining (alias to `['none']`)
-})
-```
-
-```js
-new CleanCSS({
-  inline: ['all'] // enables all inlining, same as ['local', 'remote']
-})
-```
-
-```js
-new CleanCSS({
-  inline: ['local', 'mydomain.example.com'] // enables local inlining plus given remote source
-})
-```
-
-```js
-new CleanCSS({
-  inline: ['local', 'remote', '!fonts.googleapis.com'] // enables all inlining but from given remote source
-})
-```
-
-## Optimization levels
-
-The `level` option can be either `0`, `1` (default), or `2`, e.g.
-
-```js
-new CleanCSS({
-  level: 2
-})
-```
-
-or a fine-grained configuration given via a hash.
-
-Please note that level 1 optimization options are generally safe while level 2 optimizations should be safe for most users.
-
-### Level 0 optimizations
-
-Level 0 optimizations simply means "no optimizations". Use it when you'd like to inline imports and / or rebase URLs but skip everything else.
-
-### Level 1 optimizations
-
-Level 1 optimizations (default) operate on single properties only, e.g. can remove units when not required, turn rgb colors to a shorter hex representation, remove comments, etc
-
-Here is a full list of available options:
-
-```js
-new CleanCSS({
-  level: {
-    1: {
-      cleanupCharsets: true, // controls `@charset` moving to the front of a stylesheet; defaults to `true`
-      normalizeUrls: true, // controls URL normalization; defaults to `true`
-      optimizeBackground: true, // controls `background` property optimizations; defaults to `true`
-      optimizeBorderRadius: true, // controls `border-radius` property optimizations; defaults to `true`
-      optimizeFilter: true, // controls `filter` property optimizations; defaults to `true`
-      optimizeFont: true, // controls `font` property optimizations; defaults to `true`
-      optimizeFontWeight: true, // controls `font-weight` property optimizations; defaults to `true`
-      optimizeOutline: true, // controls `outline` property optimizations; defaults to `true`
-      removeEmpty: true, // controls removing empty rules and nested blocks; defaults to `true`
-      removeNegativePaddings: true, // controls removing negative paddings; defaults to `true`
-      removeQuotes: true, // controls removing quotes when unnecessary; defaults to `true`
-      removeWhitespace: true, // controls removing unused whitespace; defaults to `true`
-      replaceMultipleZeros: true, // contols removing redundant zeros; defaults to `true`
-      replaceTimeUnits: true, // controls replacing time units with shorter values; defaults to `true`
-      replaceZeroUnits: true, // controls replacing zero values with units; defaults to `true`
-      roundingPrecision: false, // rounds pixel values to `N` decimal places; `false` disables rounding; defaults to `false`
-      selectorsSortingMethod: 'standard', // denotes selector sorting method; can be `'natural'` or `'standard'`, `'none'`, or false (the last two since 4.1.0); defaults to `'standard'`
-      specialComments: 'all', // denotes a number of /*! ... */ comments preserved; defaults to `all`
-      tidyAtRules: true, // controls at-rules (e.g. `@charset`, `@import`) optimizing; defaults to `true`
-      tidyBlockScopes: true, // controls block scopes (e.g. `@media`) optimizing; defaults to `true`
-      tidySelectors: true, // controls selectors optimizing; defaults to `true`,
-      semicolonAfterLastProperty: false, // controls removing trailing semicolons in rule; defaults to `false` - means remove
-      transform: function () {} // defines a callback for fine-grained property optimization; defaults to no-op
-    }
-  }
-});
-```
-
-There is an `all` shortcut for toggling all options at the same time, e.g.
-
-```js
-new CleanCSS({
-  level: {
-    1: {
-      all: false, // set all values to `false`
-      tidySelectors: true // turns on optimizing selectors
-    }
-  }
-});
-```
-
-### Level 2 optimizations
-
-Level 2 optimizations operate at rules or multiple properties level, e.g. can remove duplicate rules, remove properties redefined further down a stylesheet, or restructure rules by moving them around.
-
-Please note that if level 2 optimizations are turned on then, unless explicitely disabled, level 1 optimizations are applied as well.
-
-Here is a full list of available options:
-
-```js
-new CleanCSS({
-  level: {
-    2: {
-      mergeAdjacentRules: true, // controls adjacent rules merging; defaults to true
-      mergeIntoShorthands: true, // controls merging properties into shorthands; defaults to true
-      mergeMedia: true, // controls `@media` merging; defaults to true
-      mergeNonAdjacentRules: true, // controls non-adjacent rule merging; defaults to true
-      mergeSemantically: false, // controls semantic merging; defaults to false
-      overrideProperties: true, // controls property overriding based on understandability; defaults to true
-      removeEmpty: true, // controls removing empty rules and nested blocks; defaults to `true`
-      reduceNonAdjacentRules: true, // controls non-adjacent rule reducing; defaults to true
-      removeDuplicateFontRules: true, // controls duplicate `@font-face` removing; defaults to true
-      removeDuplicateMediaBlocks: true, // controls duplicate `@media` removing; defaults to true
-      removeDuplicateRules: true, // controls duplicate rules removing; defaults to true
-      removeUnusedAtRules: false, // controls unused at rule removing; defaults to false (available since 4.1.0)
-      restructureRules: false, // controls rule restructuring; defaults to false
-      skipProperties: [] // controls which properties won't be optimized, defaults to `[]` which means all will be optimized (since 4.1.0)
-    }
-  }
-});
-```
-
-There is an `all` shortcut for toggling all options at the same time, e.g.
-
-```js
-new CleanCSS({
-  level: {
-    2: {
-      all: false, // sets all values to `false`
-      removeDuplicateRules: true // turns on removing duplicate rules
-    }
-  }
-});
-```
-
-## Minify method
-
-Once configured clean-css provides a `minify` method to optimize a given CSS, e.g.
-
-```js
-var output = new CleanCSS(options).minify(source);
-```
-
-The output of the `minify` method is a hash with following fields:
-
-```js
-console.log(output.styles); // optimized output CSS as a string
-console.log(output.sourceMap); // output source map if requested with `sourceMap` option
-console.log(output.errors); // a list of errors raised
-console.log(output.warnings); // a list of warnings raised
-console.log(output.stats.originalSize); // original content size after import inlining
-console.log(output.stats.minifiedSize); // optimized content size
-console.log(output.stats.timeSpent); // time spent on optimizations in milliseconds
-console.log(output.stats.efficiency); // `(originalSize - minifiedSize) / originalSize`, e.g. 0.25 if size is reduced from 100 bytes to 75 bytes
-```
-
-The `minify` method also accepts an input source map, e.g.
-
-```js
-var output = new CleanCSS(options).minify(source, inputSourceMap);
-```
-
-or a callback invoked when optimizations are finished, e.g.
-
-```js
-new CleanCSS(options).minify(source, function (error, output) {
-  // `output` is the same as in the synchronous call above
-});
-```
-
-## Promise interface
-
-If you prefer clean-css to return a Promise object then you need to explicitely ask for it, e.g.
-
-```js
-new CleanCSS({ returnPromise: true })
-  .minify(source)
-  .then(function (output) { console.log(output.styles); })
-  .catch(function (error) { // deal with errors });
-```
-
-## CLI utility
-
-Clean-css has an associated command line utility that can be installed separately using `npm install clean-css-cli`. For more detailed information, please visit https://github.com/jakubpawlowicz/clean-css-cli.
-
-# FAQ
-
-## How to optimize multiple files?
-
-It can be done either by passing an array of paths, or, when sources are already available, a hash or an array of hashes:
-
-```js
-new CleanCSS().minify(['path/to/file/one', 'path/to/file/two']);
-```
-
-```js
-new CleanCSS().minify({
-  'path/to/file/one': {
-    styles: 'contents of file one'
-  },
-  'path/to/file/two': {
-    styles: 'contents of file two'
-  }
-});
-```
-
-```js
-new CleanCSS().minify([
-  {'path/to/file/one': {styles: 'contents of file one'}},
-  {'path/to/file/two': {styles: 'contents of file two'}}
-]);
-```
-
-Passing an array of hashes allows you to explicitly specify the order in which the input files are concatenated. Whereas when you use a single hash the order is determined by the [traversal order of object properties](http://2ality.com/2015/10/property-traversal-order-es6.html) - available since 4.1.0.
-
-Important note - any `@import` rules already present in the hash will be resolved in memory.
-
-## How to process remote `@import`s correctly?
-
-In order to inline remote `@import` statements you need to provide a callback to minify method as fetching remote assets is an asynchronous operation, e.g.:
-
-```js
-var source = '@import url(http://example.com/path/to/remote/styles);';
-new CleanCSS({ inline: ['remote'] }).minify(source, function (error, output) {
-  // output.styles
-});
-```
-
-If you don't provide a callback, then remote `@import`s will be left as is.
-
-## How to apply arbitrary transformations to CSS properties?
-
-If clean-css doesn't perform a particular property optimization, you can use `transform` callback to apply it:
-
-```js
-var source = '.block{background-image:url(/path/to/image.png)}';
-var output = new CleanCSS({
-  level: {
-    1: {
-      transform: function (propertyName, propertyValue, selector /* `selector` available since 4.2.0-pre */) {
-        if (propertyName == 'background-image' && propertyValue.indexOf('/path/to') > -1) {
-          return propertyValue.replace('/path/to', '../valid/path/to');
-        }
-      }
-    }
-  }
-}).minify(source);
-
-console.log(output.styles); # => .block{background-image:url(../valid/path/to/image.png)}
-```
-
-Note: returning `false` from `transform` callback will drop a property.
-
-## How to specify a custom rounding precision?
-
-The level 1 `roundingPrecision` optimization option accept a string with per-unit rounding precision settings, e.g.
-
-```js
-new CleanCSS({
-  level: {
-    1: {
-      roundingPrecision: 'all=3,px=5'
-    }
-  }
-}).minify(source)
-```
-
-which sets all units rounding precision to 3 digits except `px` unit precision of 5 digits.
-
-## How to keep a CSS fragment intact?
-
-Note: available in the current master, to be released in 4.2.0.
-
-Wrap the CSS fragment in special comments which instruct clean-css to preserve it, e.g.
-
-```css
-.block-1 {
-  color: red
-}
-/* clean-css ignore:start */
-.block-special {
-  color: transparent
-}
-/* clean-css ignore:end */
-.block-2 {
-  margin: 0
-}
-```
-
-Optimizing this CSS will result in the following output:
-
-```css
-.block-1{color:red}
-.block-special {
-  color: transparent
-}
-.block-2{margin:0}
-```
-
-## How to preserve a comment block?
-
-Use the `/*!` notation instead of the standard one `/*`:
-
-```css
-/*!
-  Important comments included in optimized output.
-*/
-```
-
-## How to rebase relative image URLs?
-
-clean-css will handle it automatically for you in the following cases:
-
-* when full paths to input files are passed in as options;
-* when correct paths are passed in via a hash;
-* when `rebaseTo` is used with any of above two.
-
-## How to work with source maps?
-
-To generate a source map, use `sourceMap: true` option, e.g.:
-
-```js
-new CleanCSS({ sourceMap: true, rebaseTo: pathToOutputDirectory })
-  .minify(source, function (error, output) {
-    // access output.sourceMap for SourceMapGenerator object
-    // see https://github.com/mozilla/source-map/#sourcemapgenerator for more details
-});
-```
-
-You can also pass an input source map directly as a 2nd argument to `minify` method:
-
-```js
-new CleanCSS({ sourceMap: true, rebaseTo: pathToOutputDirectory })
-  .minify(source, inputSourceMap, function (error, output) {
-    // access output.sourceMap to access SourceMapGenerator object
-    // see https://github.com/mozilla/source-map/#sourcemapgenerator for more details
-});
-```
-
-or even multiple input source maps at once:
-
-```js
-new CleanCSS({ sourceMap: true, rebaseTo: pathToOutputDirectory }).minify({
-  'path/to/source/1': {
-    styles: '...styles...',
-    sourceMap: '...source-map...'
-  },
-  'path/to/source/2': {
-    styles: '...styles...',
-    sourceMap: '...source-map...'
-  }
-}, function (error, output) {
-  // access output.sourceMap as above
-});
-```
-
-## How to apply level 1 & 2 optimizations at the same time?
-
-Using the hash configuration specifying both optimization levels, e.g.
-
-```js
-new CleanCSS({
-  level: {
-    1: {
-      all: true,
-      normalizeUrls: false
-    },
-    2: {
-      restructureRules: true
-    }
-  }
-})
-```
-
-will apply level 1 optimizations, except url normalization, and default level 2 optimizations with rule restructuring.
-
-## What level 2 optimizations do?
-
-All level 2 optimizations are dispatched [here](https://github.com/jakubpawlowicz/clean-css/blob/master/lib/optimizer/level-2/optimize.js#L67), and this is what they do:
-
-* `recursivelyOptimizeBlocks` - does all the following operations on a nested block, like `@media` or `@keyframe`;
-* `recursivelyOptimizeProperties` - optimizes properties in rulesets and flat at-rules, like @font-face, by splitting them into components (e.g. `margin` into `margin-(bottom|left|right|top)`), optimizing, and restoring them back. You may want to use `mergeIntoShorthands` option to control whether you want to turn multiple components into shorthands;
-* `removeDuplicates` - gets rid of duplicate rulesets with exactly the same set of properties, e.g. when including a Sass / Less partial twice for no good reason;
-* `mergeAdjacent` - merges adjacent rulesets with the same selector or rules;
-* `reduceNonAdjacent` - identifies which properties are overridden in same-selector non-adjacent rulesets, and removes them;
-* `mergeNonAdjacentBySelector` - identifies same-selector non-adjacent rulesets which can be moved (!) to be merged, requires all intermediate rulesets to not redefine the moved properties, or if redefined to have the same value;
-* `mergeNonAdjacentByBody` - same as the one above but for same-selector non-adjacent rulesets;
-* `restructure` - tries to reorganize different-selector different-rules rulesets so they take less space, e.g. `.one{padding:0}.two{margin:0}.one{margin-bottom:3px}` into `.two{margin:0}.one{padding:0;margin-bottom:3px}`;
-* `removeDuplicateFontAtRules` - removes duplicated `@font-face` rules;
-* `removeDuplicateMediaQueries` - removes duplicated `@media` nested blocks;
-* `mergeMediaQueries` - merges non-adjacent `@media` at-rules by the same rules as `mergeNonAdjacentBy*` above;
-

-// Possible options:
-//
-// * components: array (Only specify for shorthand properties.)

-//
-// * canOverride: function
-//   Returns whether two tokens of this property can be merged with each other.
-//   This property has no meaning for shorthands.
-//
-// * defaultValue: string
-//   Specifies the default value of the property according to the CSS standard.
-//   For shorthand, this is used when every component is set to its default value, therefore it should be the shortest possible default value of all the components.
-//
-// * shortestValue: string
-//   Specifies the shortest possible value the property can possibly have.
-//   (Falls back to defaultValue if unspecified.)
-//
-// * breakUp: function (Only specify for shorthand properties.)
-//   Breaks the shorthand up to its components.

-// * restore: function (Only specify for shorthand properties.)

-# Node.js version support
-
-clean-css requires Node.js 4.0+ (tested on Linux, OS X, and Windows)
-
-# Install
-
-```
-npm install --save-dev clean-css
-```
-
-# Use
-
-```js
-var CleanCSS = require('clean-css');
-var input = 'a{font-weight:bold;}';
-var options = { /* options */ };
-var output = new CleanCSS(options).minify(input);
-```
-
-## Important: 4.0 breaking changes
-
-clean-css 4.0 introduces some breaking changes:
-
-* API and CLI interfaces are split, so API stays in this repository while CLI moves to [clean-css-cli](https://github.com/jakubpawlowicz/clean-css-cli);
-* `root`, `relativeTo`, and `target` options are replaced by a single `rebaseTo` option - this means that rebasing URLs and import inlining is much simpler but may not be (YMMV) as powerful as in 3.x;
-* `debug` option is gone as stats are always provided in output object under `stats` property;
-* `roundingPrecision` is disabled by default;
-* `roundingPrecision` applies to **all** units now, not only `px` as in 3.x;
-* `processImport` and `processImportFrom` are merged into `inline` option which defaults to `local`. Remote `@import` rules are **NOT** inlined by default anymore;
-* splits `inliner: { request: ..., timeout: ... }` option into `inlineRequest` and `inlineTimeout` options;
-* remote resources without a protocol, e.g. `//fonts.googleapis.com/css?family=Domine:700`, are not inlined anymore;
-* changes default Internet Explorer compatibility from 9+ to 10+, to revert the old default use `{ compatibility: 'ie9' }` flag;
-* renames `keepSpecialComments` to `specialComments`;
-* moves `roundingPrecision` and `specialComments` to level 1 optimizations options, see examples;
-* moves `mediaMerging`, `restructuring`, `semanticMerging`, and `shorthandCompacting` to level 2 optimizations options, see examples below;
-* renames `shorthandCompacting` option to `mergeIntoShorthands`;
-* level 1 optimizations are the new default, up to 3.x it was level 2;
-* `keepBreaks` option is replaced with `{ format: 'keep-breaks' }` to ease transition;
-* `sourceMap` option has to be a boolean from now on - to specify an input source map pass it a 2nd argument to `minify` method or via a hash instead;
-* `aggressiveMerging` option is removed as aggressive merging is replaced by smarter override merging.
-
-## What's new in version 4.1
-
-clean-css 4.1 introduces the following changes / features:
-
-* `inline: false` as an alias to `inline: ['none']`;
-* `multiplePseudoMerging` compatibility flag controlling merging of rules with multiple pseudo classes / elements;
-* `removeEmpty` flag in level 1 optimizations controlling removal of rules and nested blocks;
-* `removeEmpty` flag in level 2 optimizations controlling removal of rules and nested blocks;
-* `compatibility: { selectors: { mergeLimit: <number> } }` flag in compatibility settings controlling maximum number of selectors in a single rule;
-* `minify` method improved signature accepting a list of hashes for a predictable traversal;
-* `selectorsSortingMethod` level 1 optimization allows `false` or `'none'` for disabling selector sorting;
-* `fetch` option controlling a function for handling remote requests;
-* new `font` shorthand and `font-*` longhand optimizers;
-* removal of `optimizeFont` flag in level 1 optimizations due to new `font` shorthand optimizer;
-* `skipProperties` flag in level 2 optimizations controlling which properties won't be optimized;
-* new `animation` shorthand and `animation-*` longhand optimizers;
-* `removeUnusedAtRules` level 2 optimization controlling removal of unused `@counter-style`, `@font-face`, `@keyframes`, and `@namespace` at rules;
-* the [web interface](https://jakubpawlowicz.github.io/clean-css) gets an improved settings panel with "reset to defaults", instant option changes, and settings being persisted across sessions.
-
-## What's new in version 4.2
-
-clean-css 4.2 introduces the following changes / features:
-
-* Adds `process` method for compatibility with optimize-css-assets-webpack-plugin;
-* new `transition` property optimizer;
-* preserves any CSS content between `/* clean-css ignore:start */` and `/* clean-css ignore:end */` comments;
-* allows filtering based on selector in `transform` callback, see [example](#how-to-apply-arbitrary-transformations-to-css-properties);
-* adds configurable line breaks via `format: { breakWith: 'lf' }` option.
-
-## Constructor options
-
-clean-css constructor accepts a hash as a parameter with the following options available:
-
-* `compatibility` - controls compatibility mode used; defaults to `ie10+`; see [compatibility modes](#compatibility-modes) for examples;
-* `fetch` - controls a function for handling remote requests; see [fetch option](#fetch-option) for examples (since 4.1.0);
-* `format` - controls output CSS formatting; defaults to `false`; see [formatting options](#formatting-options) for examples;
-* `inline` - controls `@import` inlining rules; defaults to `'local'`; see [inlining options](#inlining-options) for examples;
-* `inlineRequest` - controls extra options for inlining remote `@import` rules, can be any of [HTTP(S) request options](https://nodejs.org/api/http.html#http_http_request_options_callback);
-* `inlineTimeout` - controls number of milliseconds after which inlining a remote `@import` fails; defaults to 5000;
-* `level` - controls optimization level used; defaults to `1`; see [optimization levels](#optimization-levels) for examples;
-* `rebase` - controls URL rebasing; defaults to `true`;
-* `rebaseTo` - controls a directory to which all URLs are rebased, most likely the directory under which the output file will live; defaults to the current directory;
-* `returnPromise` - controls whether `minify` method returns a Promise object or not; defaults to `false`; see [promise interface](#promise-interface) for examples;
-* `sourceMap` - controls whether an output source map is built; defaults to `false`;
-* `sourceMapInlineSources` - controls embedding sources inside a source map's `sourcesContent` field; defaults to false.
-
-## Compatibility modes
-
-There is a certain number of compatibility mode shortcuts, namely:
-
-* `new CleanCSS({ compatibility: '*' })` (default) - Internet Explorer 10+ compatibility mode
-* `new CleanCSS({ compatibility: 'ie9' })` - Internet Explorer 9+ compatibility mode
-* `new CleanCSS({ compatibility: 'ie8' })` - Internet Explorer 8+ compatibility mode
-* `new CleanCSS({ compatibility: 'ie7' })` - Internet Explorer 7+ compatibility mode
-
-Each of these modes is an alias to a [fine grained configuration](https://github.com/jakubpawlowicz/clean-css/blob/master/lib/options/compatibility.js), with the following options available:
-
-```js
-new CleanCSS({
-  compatibility: {
-    colors: {
-      opacity: true // controls `rgba()` / `hsla()` color support
-    },
-    properties: {
-      backgroundClipMerging: true, // controls background-clip merging into shorthand
-      backgroundOriginMerging: true, // controls background-origin merging into shorthand
-      backgroundSizeMerging: true, // controls background-size merging into shorthand
-      colors: true, // controls color optimizations
-      ieBangHack: false, // controls keeping IE bang hack
-      ieFilters: false, // controls keeping IE `filter` / `-ms-filter`
-      iePrefixHack: false, // controls keeping IE prefix hack
-      ieSuffixHack: false, // controls keeping IE suffix hack
-      merging: true, // controls property merging based on understandability
-      shorterLengthUnits: false, // controls shortening pixel units into `pc`, `pt`, or `in` units
-      spaceAfterClosingBrace: true, // controls keeping space after closing brace - `url() no-repeat` into `url()no-repeat`
-      urlQuotes: false, // controls keeping quoting inside `url()`
-      zeroUnits: true // controls removal of units `0` value
-    },
-    selectors: {
-      adjacentSpace: false, // controls extra space before `nav` element
-      ie7Hack: true, // controls removal of IE7 selector hacks, e.g. `*+html...`
-      mergeablePseudoClasses: [':active', ...], // controls a whitelist of mergeable pseudo classes
-      mergeablePseudoElements: ['::after', ...], // controls a whitelist of mergeable pseudo elements
-      mergeLimit: 8191, // controls maximum number of selectors in a single rule (since 4.1.0)
-      multiplePseudoMerging: true // controls merging of rules with multiple pseudo classes / elements (since 4.1.0)
-    },
-    units: {
-      ch: true, // controls treating `ch` as a supported unit
-      in: true, // controls treating `in` as a supported unit
-      pc: true, // controls treating `pc` as a supported unit
-      pt: true, // controls treating `pt` as a supported unit
-      rem: true, // controls treating `rem` as a supported unit
-      vh: true, // controls treating `vh` as a supported unit
-      vm: true, // controls treating `vm` as a supported unit
-      vmax: true, // controls treating `vmax` as a supported unit
-      vmin: true // controls treating `vmin` as a supported unit
-    }
-  }
-})
-```
-
-You can also use a string when setting a compatibility mode, e.g.
-
-```js
-new CleanCSS({
-  compatibility: 'ie9,-properties.merging' // sets compatibility to IE9 mode with disabled property merging
-})
-```
-
-## Fetch option
-
-The `fetch` option accepts a function which handles remote resource fetching, e.g.
-
-```js
-var request = require('request');
-var source = '@import url(http://example.com/path/to/stylesheet.css);';
-new CleanCSS({
-  fetch: function (uri, inlineRequest, inlineTimeout, callback) {
-    request(uri, function (error, response, body) {
-      if (error) {
-        callback(error, null);
-      } else if (response && response.statusCode != 200) {
-        callback(response.statusCode, null);
-      } else {
-        callback(null, body);
-      }
-    });
-  }
-}).minify(source);
-```
-
-This option provides a convenient way of overriding the default fetching logic if it doesn't support a particular feature, say CONNECT proxies.
-
-Unless given, the default [loadRemoteResource](https://github.com/jakubpawlowicz/clean-css/blob/master/lib/reader/load-remote-resource.js) logic is used.
-
-## Formatting options
-
-By default output CSS is formatted without any whitespace unless a `format` option is given.
-First of all there are two shorthands:
-
-```js
-new CleanCSS({
-  format: 'beautify' // formats output in a really nice way
-})
-```
-
-and
-
-```js
-new CleanCSS({
-  format: 'keep-breaks' // formats output the default way but adds line breaks for improved readability
-})
-```
-
-however `format` option also accept a fine-grained set of options:
-
-```js
-new CleanCSS({
-  format: {
-    breaks: { // controls where to insert breaks
-      afterAtRule: false, // controls if a line break comes after an at-rule; e.g. `@charset`; defaults to `false`
-      afterBlockBegins: false, // controls if a line break comes after a block begins; e.g. `@media`; defaults to `false`
-      afterBlockEnds: false, // controls if a line break comes after a block ends, defaults to `false`
-      afterComment: false, // controls if a line break comes after a comment; defaults to `false`
-      afterProperty: false, // controls if a line break comes after a property; defaults to `false`
-      afterRuleBegins: false, // controls if a line break comes after a rule begins; defaults to `false`
-      afterRuleEnds: false, // controls if a line break comes after a rule ends; defaults to `false`
-      beforeBlockEnds: false, // controls if a line break comes before a block ends; defaults to `false`
-      betweenSelectors: false // controls if a line break comes between selectors; defaults to `false`
-    },
-    breakWith: '\n', // controls the new line character, can be `'\r\n'` or `'\n'` (aliased as `'windows'` and `'unix'` or `'crlf'` and `'lf'`); defaults to system one, so former on Windows and latter on Unix
-    indentBy: 0, // controls number of characters to indent with; defaults to `0`
-    indentWith: 'space', // controls a character to indent with, can be `'space'` or `'tab'`; defaults to `'space'`
-    spaces: { // controls where to insert spaces
-      aroundSelectorRelation: false, // controls if spaces come around selector relations; e.g. `div > a`; defaults to `false`
-      beforeBlockBegins: false, // controls if a space comes before a block begins; e.g. `.block {`; defaults to `false`
-      beforeValue: false // controls if a space comes before a value; e.g. `width: 1rem`; defaults to `false`
-    },
-    wrapAt: false // controls maximum line length; defaults to `false`
-  }
-})
-```
-
-## Inlining options
-
-`inline` option whitelists which `@import` rules will be processed, e.g.
-
-```js
-new CleanCSS({
-  inline: ['local'] // default; enables local inlining only
-})
-```
-
-```js
-new CleanCSS({
-  inline: ['none'] // disables all inlining
-})
-```
-
-```js
-// introduced in clean-css 4.1.0
-
-new CleanCSS({
-  inline: false // disables all inlining (alias to `['none']`)
-})
-```
-
-```js
-new CleanCSS({
-  inline: ['all'] // enables all inlining, same as ['local', 'remote']
-})
-```
-
-```js
-new CleanCSS({
-  inline: ['local', 'mydomain.example.com'] // enables local inlining plus given remote source
-})
-```
-
-```js
-new CleanCSS({
-  inline: ['local', 'remote', '!fonts.googleapis.com'] // enables all inlining but from given remote source
-})
-```
-

-The `level` option can be either `0`, `1` (default), or `2`, e.g.
-
-```js
-new CleanCSS({
-  level: 2
-})
-```
-
-or a fine-grained configuration given via a hash.
-
-Please note that level 1 optimization options are generally safe while level 2 optimizations should be safe for most users.
-
-### Level 0 optimizations
-
-Level 0 optimizations simply means "no optimizations". Use it when you'd like to inline imports and / or rebase URLs but skip everything else.
-
-### Level 1 optimizations
-
-Level 1 optimizations (default) operate on single properties only, e.g. can remove units when not required, turn rgb colors to a shorter hex representation, remove comments, etc
-
-Here is a full list of available options:
-
-```js
-new CleanCSS({
-  level: {
-    1: {
-      cleanupCharsets: true, // controls `@charset` moving to the front of a stylesheet; defaults to `true`
-      normalizeUrls: true, // controls URL normalization; defaults to `true`
-      optimizeBackground: true, // controls `background` property optimizations; defaults to `true`
-      optimizeBorderRadius: true, // controls `border-radius` property optimizations; defaults to `true`
-      optimizeFilter: true, // controls `filter` property optimizations; defaults to `true`
-      optimizeFont: true, // controls `font` property optimizations; defaults to `true`
-      optimizeFontWeight: true, // controls `font-weight` property optimizations; defaults to `true`
-      optimizeOutline: true, // controls `outline` property optimizations; defaults to `true`
-      removeEmpty: true, // controls removing empty rules and nested blocks; defaults to `true`
-      removeNegativePaddings: true, // controls removing negative paddings; defaults to `true`
-      removeQuotes: true, // controls removing quotes when unnecessary; defaults to `true`
-      removeWhitespace: true, // controls removing unused whitespace; defaults to `true`
-      replaceMultipleZeros: true, // contols removing redundant zeros; defaults to `true`
-      replaceTimeUnits: true, // controls replacing time units with shorter values; defaults to `true`
-      replaceZeroUnits: true, // controls replacing zero values with units; defaults to `true`
-      roundingPrecision: false, // rounds pixel values to `N` decimal places; `false` disables rounding; defaults to `false`
-      selectorsSortingMethod: 'standard', // denotes selector sorting method; can be `'natural'` or `'standard'`, `'none'`, or false (the last two since 4.1.0); defaults to `'standard'`
-      specialComments: 'all', // denotes a number of /*! ... */ comments preserved; defaults to `all`
-      tidyAtRules: true, // controls at-rules (e.g. `@charset`, `@import`) optimizing; defaults to `true`
-      tidyBlockScopes: true, // controls block scopes (e.g. `@media`) optimizing; defaults to `true`
-      tidySelectors: true, // controls selectors optimizing; defaults to `true`,
-      semicolonAfterLastProperty: false, // controls removing trailing semicolons in rule; defaults to `false` - means remove
-      transform: function () {} // defines a callback for fine-grained property optimization; defaults to no-op
-    }
-  }
-});
-```
-
-There is an `all` shortcut for toggling all options at the same time, e.g.
-
-```js
-new CleanCSS({
-  level: {
-    1: {
-      all: false, // set all values to `false`
-      tidySelectors: true // turns on optimizing selectors
-    }
-  }
-});
-```
-
-### Level 2 optimizations
-
-Level 2 optimizations operate at rules or multiple properties level, e.g. can remove duplicate rules, remove properties redefined further down a stylesheet, or restructure rules by moving them around.
-
-Please note that if level 2 optimizations are turned on then, unless explicitely disabled, level 1 optimizations are applied as well.
-
-Here is a full list of available options:
-
-```js
-new CleanCSS({
-  level: {
-    2: {
-      mergeAdjacentRules: true, // controls adjacent rules merging; defaults to true
-      mergeIntoShorthands: true, // controls merging properties into shorthands; defaults to true
-      mergeMedia: true, // controls `@media` merging; defaults to true
-      mergeNonAdjacentRules: true, // controls non-adjacent rule merging; defaults to true
-      mergeSemantically: false, // controls semantic merging; defaults to false
-      overrideProperties: true, // controls property overriding based on understandability; defaults to true
-      removeEmpty: true, // controls removing empty rules and nested blocks; defaults to `true`
-      reduceNonAdjacentRules: true, // controls non-adjacent rule reducing; defaults to true
-      removeDuplicateFontRules: true, // controls duplicate `@font-face` removing; defaults to true
-      removeDuplicateMediaBlocks: true, // controls duplicate `@media` removing; defaults to true
-      removeDuplicateRules: true, // controls duplicate rules removing; defaults to true
-      removeUnusedAtRules: false, // controls unused at rule removing; defaults to false (available since 4.1.0)
-      restructureRules: false, // controls rule restructuring; defaults to false
-      skipProperties: [] // controls which properties won't be optimized, defaults to `[]` which means all will be optimized (since 4.1.0)
-    }
-  }
-});
-```
-
-There is an `all` shortcut for toggling all options at the same time, e.g.
-
-```js
-new CleanCSS({
-  level: {
-    2: {
-      all: false, // sets all values to `false`
-      removeDuplicateRules: true // turns on removing duplicate rules
-    }
-  }
-});
-```
-
-## Minify method
-
-Once configured clean-css provides a `minify` method to optimize a given CSS, e.g.
-
-```js
-var output = new CleanCSS(options).minify(source);
-```
-
-The output of the `minify` method is a hash with following fields:
-
-```js
-console.log(output.styles); // optimized output CSS as a string
-console.log(output.sourceMap); // output source map if requested with `sourceMap` option
-console.log(output.errors); // a list of errors raised
-console.log(output.warnings); // a list of warnings raised
-console.log(output.stats.originalSize); // original content size after import inlining
-console.log(output.stats.minifiedSize); // optimized content size
-console.log(output.stats.timeSpent); // time spent on optimizations in milliseconds
-console.log(output.stats.efficiency); // `(originalSize - minifiedSize) / originalSize`, e.g. 0.25 if size is reduced from 100 bytes to 75 bytes
-```
-
-The `minify` method also accepts an input source map, e.g.
-
-```js
-var output = new CleanCSS(options).minify(source, inputSourceMap);
-```
-
-or a callback invoked when optimizations are finished, e.g.
-
-```js
-new CleanCSS(options).minify(source, function (error, output) {
-  // `output` is the same as in the synchronous call above
-});
-```
-
-## Promise interface
-
-If you prefer clean-css to return a Promise object then you need to explicitely ask for it, e.g.
-
-```js
-new CleanCSS({ returnPromise: true })
-  .minify(source)
-  .then(function (output) { console.log(output.styles); })
-  .catch(function (error) { // deal with errors });
-```
-
-## CLI utility
-
-Clean-css has an associated command line utility that can be installed separately using `npm install clean-css-cli`. For more detailed information, please visit https://github.com/jakubpawlowicz/clean-css-cli.
-
-# FAQ
-
-## How to optimize multiple files?
-
-It can be done either by passing an array of paths, or, when sources are already available, a hash or an array of hashes:
-
-```js
-new CleanCSS().minify(['path/to/file/one', 'path/to/file/two']);
-```
-
-```js
-new CleanCSS().minify({
-  'path/to/file/one': {
-    styles: 'contents of file one'
-  },
-  'path/to/file/two': {
-    styles: 'contents of file two'
-  }
-});
-```
-
-```js
-new CleanCSS().minify([
-  {'path/to/file/one': {styles: 'contents of file one'}},
-  {'path/to/file/two': {styles: 'contents of file two'}}
-]);
-```
-
-Passing an array of hashes allows you to explicitly specify the order in which the input files are concatenated. Whereas when you use a single hash the order is determined by the [traversal order of object properties](http://2ality.com/2015/10/property-traversal-order-es6.html) - available since 4.1.0.
-
-Important note - any `@import` rules already present in the hash will be resolved in memory.
-
-## How to process remote `@import`s correctly?
-
-In order to inline remote `@import` statements you need to provide a callback to minify method as fetching remote assets is an asynchronous operation, e.g.:
-
-```js
-var source = '@import url(http://example.com/path/to/remote/styles);';
-new CleanCSS({ inline: ['remote'] }).minify(source, function (error, output) {
-  // output.styles
-});
-```
-
-If you don't provide a callback, then remote `@import`s will be left as is.
-
-## How to apply arbitrary transformations to CSS properties?
-
-If clean-css doesn't perform a particular property optimization, you can use `transform` callback to apply it:
-
-```js
-var source = '.block{background-image:url(/path/to/image.png)}';
-var output = new CleanCSS({
-  level: {
-    1: {
-      transform: function (propertyName, propertyValue, selector /* `selector` available since 4.2.0-pre */) {
-        if (propertyName == 'background-image' && propertyValue.indexOf('/path/to') > -1) {
-          return propertyValue.replace('/path/to', '../valid/path/to');
-        }
-      }
-    }
-  }
-}).minify(source);
-
-console.log(output.styles); # => .block{background-image:url(../valid/path/to/image.png)}
-```
-
-Note: returning `false` from `transform` callback will drop a property.
-
-## How to specify a custom rounding precision?
-
-The level 1 `roundingPrecision` optimization option accept a string with per-unit rounding precision settings, e.g.
-
-```js
-new CleanCSS({
-  level: {
-    1: {
-      roundingPrecision: 'all=3,px=5'
-    }
-  }
-}).minify(source)
-```
-
-which sets all units rounding precision to 3 digits except `px` unit precision of 5 digits.
-
-## How to keep a CSS fragment intact?
-
-Note: available in the current master, to be released in 4.2.0.
-
-Wrap the CSS fragment in special comments which instruct clean-css to preserve it, e.g.
-
-```css
-.block-1 {
-  color: red
-}
-/* clean-css ignore:start */
-.block-special {
-  color: transparent
-}
-/* clean-css ignore:end */
-.block-2 {
-  margin: 0
-}
-```
-
-Optimizing this CSS will result in the following output:
-
-```css
-.block-1{color:red}
-.block-special {
-  color: transparent
-}
-.block-2{margin:0}
-```
-
-## How to preserve a comment block?
-
-Use the `/*!` notation instead of the standard one `/*`:
-
-```css
-/*!
-  Important comments included in optimized output.
-*/
-```
-
-## How to rebase relative image URLs?
-
-clean-css will handle it automatically for you in the following cases:
-
-* when full paths to input files are passed in as options;
-* when correct paths are passed in via a hash;
-* when `rebaseTo` is used with any of above two.
-
-## How to work with source maps?
-
-To generate a source map, use `sourceMap: true` option, e.g.:
-
-```js
-new CleanCSS({ sourceMap: true, rebaseTo: pathToOutputDirectory })
-  .minify(source, function (error, output) {
-    // access output.sourceMap for SourceMapGenerator object
-    // see https://github.com/mozilla/source-map/#sourcemapgenerator for more details
-});
-```
-
-You can also pass an input source map directly as a 2nd argument to `minify` method:
-
-```js
-new CleanCSS({ sourceMap: true, rebaseTo: pathToOutputDirectory })
-  .minify(source, inputSourceMap, function (error, output) {
-    // access output.sourceMap to access SourceMapGenerator object
-    // see https://github.com/mozilla/source-map/#sourcemapgenerator for more details
-});
-```
-
-or even multiple input source maps at once:
-
-```js
-new CleanCSS({ sourceMap: true, rebaseTo: pathToOutputDirectory }).minify({
-  'path/to/source/1': {
-    styles: '...styles...',
-    sourceMap: '...source-map...'
-  },
-  'path/to/source/2': {
-    styles: '...styles...',
-    sourceMap: '...source-map...'
-  }
-}, function (error, output) {
-  // access output.sourceMap as above
-});
-```
-
-## How to apply level 1 & 2 optimizations at the same time?
-
-Using the hash configuration specifying both optimization levels, e.g.
-
-```js
-new CleanCSS({
-  level: {
-    1: {
-      all: true,
-      normalizeUrls: false
-    },
-    2: {
-      restructureRules: true
-    }
-  }
-})
-```
-
-will apply level 1 optimizations, except url normalization, and default level 2 optimizations with rule restructuring.
-
-## What level 2 optimizations do?
-
-All level 2 optimizations are dispatched [here](https://github.com/jakubpawlowicz/clean-css/blob/master/lib/optimizer/level-2/optimize.js#L67), and this is what they do:
-
-* `recursivelyOptimizeBlocks` - does all the following operations on a nested block, like `@media` or `@keyframe`;
-* `recursivelyOptimizeProperties` - optimizes properties in rulesets and flat at-rules, like @font-face, by splitting them into components (e.g. `margin` into `margin-(bottom|left|right|top)`), optimizing, and restoring them back. You may want to use `mergeIntoShorthands` option to control whether you want to turn multiple components into shorthands;
-* `removeDuplicates` - gets rid of duplicate rulesets with exactly the same set of properties, e.g. when including a Sass / Less partial twice for no good reason;
-* `mergeAdjacent` - merges adjacent rulesets with the same selector or rules;
-* `reduceNonAdjacent` - identifies which properties are overridden in same-selector non-adjacent rulesets, and removes them;
-* `mergeNonAdjacentBySelector` - identifies same-selector non-adjacent rulesets which can be moved (!) to be merged, requires all intermediate rulesets to not redefine the moved properties, or if redefined to have the same value;
-* `mergeNonAdjacentByBody` - same as the one above but for same-selector non-adjacent rulesets;
-* `restructure` - tries to reorganize different-selector different-rules rulesets so they take less space, e.g. `.one{padding:0}.two{margin:0}.one{margin-bottom:3px}` into `.two{margin:0}.one{padding:0;margin-bottom:3px}`;
-* `removeDuplicateFontAtRules` - removes duplicated `@font-face` rules;
-* `removeDuplicateMediaQueries` - removes duplicated `@media` nested blocks;
-* `mergeMediaQueries` - merges non-adjacent `@media` at-rules by the same rules as `mergeNonAdjacentBy*` above;
-

-// Properties to process
-// Extend this object in order to add support for more properties in the optimizer.
-//
-// Each key in this object represents a CSS property and should be an object.
-// Such an object contains properties that describe how the represented CSS property should be handled.
-// Possible options:
-//
-// * components: array (Only specify for shorthand properties.)
-//   Contains the names of the granular properties this shorthand compacts.
-//
-// * canOverride: function
-//   Returns whether two tokens of this property can be merged with each other.
-//   This property has no meaning for shorthands.
-//
-// * defaultValue: string
-//   Specifies the default value of the property according to the CSS standard.
-//   For shorthand, this is used when every component is set to its default value, therefore it should be the shortest possible default value of all the components.
-//
-// * shortestValue: string
-//   Specifies the shortest possible value the property can possibly have.
-//   (Falls back to defaultValue if unspecified.)
-//
-// * breakUp: function (Only specify for shorthand properties.)
-//   Breaks the shorthand up to its components.
-//
-// * restore: function (Only specify for shorthand properties.)
-//   Puts the shorthand together from its components.
