# postcss-selector-matches [![CSS Standard Status](https://cssdb.org/badge/matches-pseudo-class.svg)](https://cssdb.org/#matches-pseudo-class) [![Build Status](https://travis-ci.org/postcss/postcss-selector-matches.svg?branch=master)](https://travis-ci.org/postcss/postcss-selector-matches) > PostCSS plugin to transform `:matches()` W3C CSS pseudo class to more compatible CSS selectors http://dev.w3.org/csswg/selectors-4/#matches ## Installation ```console $ npm install postcss-selector-matches ``` ## Usage ```js var postcss = require("postcss") var output = postcss() .use(require("postcss-selector-matches")) .process(require("fs").readFileSync("input.css", "utf8")) .css ``` Using this `input.css`: ```css p:matches(:first-child, .special) { color: red; } ``` you will get: ```css p:first-child, p.special { color: red; } ``` **Note that if you are doing crazy selector like `p:matches(a) {}` you are likely to get crazy results (like `pa {}`)**. ## Options ### `lineBreak` (default: `false`) Allows you to introduce a line break between generated selectors. --- ## [Changelog](CHANGELOG.md) ## [License](LICENSE)
