Adapt.js responsive without bootstrap

What is this?


 Adapt.js is a lightweight (848 bytes minified) JavaScript file that determines which CSS file to load before the browser renders a page. If the browser tilts or resizes, Adapt.js simply checks its width, and serves only the CSS that is needed, when it is needed.



 http://adapt.960.gs/

// Edit to suit your needs.
var ADAPT_CONFIG = {
  // Where is your CSS?
  path: 'assets/css/',

  // false = Only run once, when page first loads.
  // true = Change on window resize and page tilt.
  dynamic: true,

  // Optional callback... myCallback(i, width)
  callback: myCallback,

  // First range entry is the minimum.
  // Last range entry is the maximum.
  // Separate ranges by "to" keyword.
  range: [
    '0px    to 760px  = mobile.css',
    '760px  to 980px  = 720.css',
    '980px  to 1280px = 960.css',
    '1280px to 1600px = 1200.css',
    '1600px to 1920px = 1560.css',
    '1940px to 2540px = 1920.css',
    '2540px           = 2520.css'
  ]
};
