Mobilizer

Extract mobile stylesheet from responsive css files

Description

mobilizer is a node.js module that allows you to strip :hover styles and media-queries from a responsive css, creating smaller stylesheets that are better suitable for touch devices and small screens.

Install

npm install mobilizer --save-dev

Usage

var mobilizer = require("mobilizer");
 
mobilizer(src, {
 
  mobile: { 
    
    // No :hover styles
    // skip media queries that wont match a screen of 0px:
    // @media(min-width: 300px) {} won't match
    // @media(max-width: 300px) {} will match
 
    hover: 'exclude',
    screens: [ '0px' ]
  },
 
  tablet: { // small screens and a little bigger
    hover: 'exclude',
    screens: [ '0px', '700px' ]
  },
  
 
  hover: {
    // skip rules including :hover styles only,
    // useful if you decide to re-add :hover using a separate file
    hover: 'only',
 
    // matches all screens
    screens: 'any'
  }
 
  desktop: {
    // includes any rule, including :hover styles
    // but excludes anything outside media queries
    media: 'only',
 
    // matches bigger screen media queries only
    screens: [ '1024px' ]
  }
 
  noMediaQueries: {
    // matches anything but media queries
    media: 'exclude'
  }
 
});

This would return an object like this:

{
  mobile: '...stylesheet content...',
  tablet: '...stylesheet content...',
  hover: '...stylesheet content...',
  desktop: '...stylesheet content...'
}

A note about safety

Mobilizer retains order of rules as they are declared in input sources so it is generally safe to apply it.

Just be careful when you try to recombine mobilizer stylesheets together. I.e.

mobilizer(bootstrap_css, {
  'mobile.css': {
    media: 'exclude',
    hover: 'exclude'
  },
  'responsive.css': {
    media: 'only',
    hover: 'exclude'  
  },
  'hover.css': {
    hover: 'only'
  }
});
<!-- Correct -->
<head>
  <link href='hover.css'></link>
  <link href='mobile.css'></link>
  <link href='responsive.css'></link>
</head>
<!-- Wrong -->
<head>
  <link href='hover.css'></link>
  <link href='responsive.css'></link>
  <link href='mobile.css'></link>
</head>
