css3-mediaqueries-js
css3-mediaqueries.js is a JavaScript library that makes CSS3 media queries work in all browsers.
Browser support: IE 5+, Firefox 1+ and Safari 2. Firefox 3.5+, Opera 7+, Safari 3+ and Chrome already offer native support for CSS3 media queries.
Installation
Include a link to the script somewhere on the page (whether in the <head> or before </body>)
<script src="/js/css3-mediaqueries.min.js"></script>
And that's it! Keep in mind that the script will not detect media attributes on <link> elements, so it is recommended to use the @media property within the stylesheets themselves.
