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.
