rework

CSS manipulations built on css, allowing you to automate vendor prefixing, create your own properties, inline images, anything you can imagine!

Please refer to css for AST documentation and to report parser/stringifier issues.

Installation

$ npm install rework

Usage

var rework = require('rework');
var pluginA = require('pluginA');
var pluginB = require('pluginB');

rework('body { font-size: 12px; }', { source: 'source.css' })
  .use(pluginA)
  .use(pluginB)
  .toString({ sourcemap: true })

API

rework(code, [options])

Accepts a CSS string and returns a new Rework instance. The options are passed directly to css.parse.

Rework#use(fn)

Use the given plugin fn. A rework "plugin" is simply a function accepting the stylesheet root node and the Rework instance.

Rework#toString([options])

Returns the string representation of the manipulated CSS. The options are passed directly to css.stringify.

Unlike css.stringify, if you pass sourcemap: true a string will still be returned, with the source map inlined. Also use sourcemapAsObject: true if you want the css.stringify return value.

Plugins

Rework has a rich collection of plugins and mixins. Browse all the Rework plugins available on npm.
