[Here’s an online demo.](http://mothereff.in/css-escapes) + +Feel free to fork if you see possible improvements! + +## Installation + +Via [Bower](http://bower.io/): + +```bash +bower install cssesc +``` + +Via [Component](https://github.com/component/component): + +```bash +component install mathiasbynens/cssesc +``` + +Via [npm](http://npmjs.org/): + +```bash +npm install cssesc +``` + +In a browser: + +```html +<script src="cssesc.js"></script> +``` + +In [Node.js](http://nodejs.org/) and [RingoJS](http://ringojs.org/): + +```js +var cssesc = require('cssesc'); +``` + +In [Narwhal](http://narwhaljs.org/): + +```js +var cssesc = require('cssesc').cssesc; +``` + +In [Rhino](http://www.mozilla.org/rhino/): + +```js +load('cssesc.js'); +``` + +Using an AMD loader like [RequireJS](http://requirejs.org/): + +```js +require( + { + 'paths': { + 'cssesc': 'path/to/cssesc' + } + }, + ['cssesc'], + function(cssesc) { + console.log(cssesc); + } +); +``` + +## API + +### `cssesc(value, options)` + +This function takes a value and returns an escaped version of the value where any characters that are not printable ASCII symbols are escaped using the shortest possible (but valid) [escape sequences for use in CSS strings or identifiers](http://mathiasbynens.be/notes/css-escapes). + +```js +cssesc('Ich ♥ Bücher'); +// → 'Ich \\2665 B\\FC cher' + +cssesc('foo 𝌆 bar'); +// → 'foo \\1D306 bar' +``` + +By default, `cssesc` returns a string that can be used as part of a CSS string. If the target is a CSS identifier rather than a CSS string, use the `isIdentifier: true` setting (see below). + +The optional `options` argument accepts an object with the following options: + +#### `isIdentifier` + +The default value for the `isIdentifier` option is `false`. This means that the input text will be escaped for use in a CSS string literal. If you want to use the result as a CSS identifier instead (in a selector, for example), set this option to `true`. + +```js +cssesc('123a2b'); +// → '123a2b' + +cssesc('123a2b', { + 'isIdentifier': true +}); +// → '\\31 23a2b' +``` + +#### `quotes` + +The default value for the `quotes` option is `'single'`. This means that any occurences of `'` in the input text will be escaped as `\'`, so that the output can be used in a CSS string literal wrapped in single quotes. + +```js +cssesc('Lorem ipsum "dolor" sit \'amet\' etc.'); +// → 'Lorem ipsum "dolor" sit \\\'amet\\\' etc.' +// → "Lorem ipsum \"dolor\" sit \\'amet\\' etc." + +cssesc('Lorem ipsum "dolor" sit \'amet\' etc.', { + 'quotes': 'single' +}); +// → 'Lorem ipsum "dolor" sit \\\'amet\\\' etc.' +// → "Lorem ipsum \"dolor\" sit \\'amet\\' etc." +``` + +If you want to use the output as part of a CSS string literal wrapped in double quotes, set the `quotes` option to `'double'`. + +```js +cssesc('Lorem ipsum "dolor" sit \'amet\' etc.', { + 'quotes': 'double' +}); +// → 'Lorem ipsum \\"dolor\\" sit \'amet\' etc.' +// → "Lorem ipsum \\\"dolor\\\" sit 'amet' etc." +``` + +#### `wrap` + +The `wrap` option takes a boolean value (`true` or `false`), and defaults to `false` (disabled). When enabled, the output will be a valid CSS string literal wrapped in quotes. The type of quotes can be specified through the `quotes` setting. + +```js +cssesc('Lorem ipsum "dolor" sit \'amet\' etc.', { + 'quotes': 'single', + 'wrap': true +}); +// → '\'Lorem ipsum "dolor" sit \\\'amet\\\' etc.\'' +// → "\'Lorem ipsum \"dolor\" sit \\\'amet\\\' etc.\'" + +cssesc('Lorem ipsum "dolor" sit \'amet\' etc.', { + 'quotes': 'double', + 'wrap': true +}); +// → '"Lorem ipsum \\"dolor\\" sit \'amet\' etc."' +// → "\"Lorem ipsum \\\"dolor\\\" sit \'amet\' etc.\"" +``` + +#### `escapeEverything` + +The `escapeEverything` option takes a boolean value (`true` or `false`), and defaults to `false` (disabled). When enabled, all the symbols in the output will be escaped, even printable ASCII symbols. + +```js +cssesc('lolwat"foo\'bar', { + 'escapeEverything': true +}); +// → '\\6C\\6F\\6C\\77\\61\\74\\"\\66\\6F\\6F\\\'\\62\\61\\72' +// → "\\6C\\6F\\6C\\77\\61\\74\\\"\\66\\6F\\6F\\'\\62\\61\\72" +``` + +### `cssesc.version` + +A string representing the semantic version number. + +### Using the `cssesc` binary + +To use the `cssesc` binary in your shell, simply install cssesc globally using npm: + +```bash +npm install -g cssesc +``` + +After that you will be able to escape text for use in CSS strings or identifiers from the command line: + +```bash +$ cssesc 'föo ♥ bår 𝌆 baz' +f\F6o \2665 b\E5r \1D306 baz +``` + +If the output needs to be a CSS identifier rather than part of a string literal, use the `-i`/`--identifier` option: + +```bash +$ cssesc --identifier 'föo ♥ bår 𝌆 baz' +f\F6o\ \2665\ b\E5r\ \1D306\ baz +``` + +See `cssesc --help` for the full list of options. + +## Support + +This library has been tested in at least Chrome 28-30, Firefox 3-23, Safari 4-6, Opera 10-15, IE 6-10, Node.js v0.10.0, Narwhal 0.3.2, RingoJS 0.8-0.9, PhantomJS 1.9.0, and Rhino 1.7RC4. + +## Unit tests & code coverage + +After cloning this repository, run `npm install` to install the dependencies needed for development and testing. You may want to install Istanbul _globally_ using `npm install istanbul -g`. + +Once that’s done, you can run the unit tests in Node using `npm test` or `node tests/tests.js`. To run the tests in Rhino, Ringo, Narwhal, and web browsers as well, use `grunt test`. + +To generate [the code coverage report](http://rawgithub.com/mathiasbynens/cssesc/master/coverage/cssesc/cssesc.js.html), use `grunt cover`. + +## Author + +| [](http://twitter.com/mathias "Follow @mathias on Twitter") | +|---| +| [Mathias Bynens](http://mathiasbynens.be/) | + +## License + +This library is available under the [MIT](http://mths.be/mit) license. |
