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. + +## 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; +* `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);

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 +}) +``` + +```js +new CleanCSS({ + inline: ['all'] // same as ['local', 'remote'] +}) +``` + +```js +new CleanCSS({ + inline: ['local', 'mydomain.example.com'] +}) +``` + +```js +new CleanCSS({ + inline: ['local', 'remote', '!fonts.googleapis.com'] +}) +``` + +## 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 optimizatons; defaults to `true` + optimizeBorderRadius: true, // controls `border-radius` property optimizatons; defaults to `true` + optimizeFilter: true, // controls `filter` property optimizatons; defaults to `true` + optimizeFont: true, // ontrols `font` property optimizatons; defaults to `true` + optimizeFontWeight: true, // controls `font-weight` property optimizatons;

defaults to `false` + selectorsSortingMethod: 'standard', // denotes selector sorting method; can be `natural` or `standard`; 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`, + 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 + 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 + restructureRules: false // controls rule restructuring; defaults to false + } + } +}); +``` + +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); // a ratio of output size to input size (e.g. 25% if content was 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 }); +``` + +# 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: + +```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' + } +}); +``` + +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) { + 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 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;
