Rework Split Media

Split a stylesheet into multiple stylesheets. You may want to use rework-move-media prior to using this.

API

var stylesheets = split(parse(string)) || split(rework(string))

This module can be used with rework or with css-parse. If you use it with rework, be sure to not rework().toString().

var split = require('rework-split-media')

var stylesheets = split(
  rework('body { color: red }')
    .use(require('rework-move-media')())
)

stylesheets will be an object with stylesheets[query] = stylesheet. If there's no media query, query = "". Thus, it'll look something like this:

{
  "": {
    "type": "stylesheet",
    "rules": []
  },
  "(max-width: 960px)": {
    "type": "stylesheet",
    "rules": []
  }
}

Each stylesheet will be stripped of any @media queries.

stringifying

You can stringify the stylesheets by using css-stringify.

var stringify = require('css-stringify')

var general = stringify(stylesheets[''])
var lte960px = stringify(stylesheets['(max-width: 960px)'])

Then you'll want to setup a build process to link them in your HTML appropriately:

<link rel="stylesheet" href="styles.css">
<link rel="stylesheet" media="(max-width: 960px)" href="styles-lte-960-px.css">

If you want to concatenate them, you can do:

var query = '(max-width: 960px)'
var all = general + '@media' + query + '{' + lte960px + '}'
