Selectivizr

CSS3 selectors for IE

selectivizr is a JavaScript utility that emulates CSS3 pseudo-classes and attribute selectors in Internet Explorer 6-8. Simply include the script in your pages and selectivizr will do the rest.

To use the library, you'll need to include one of the supported libraries:

• jQuery (1.3+/1.4+)
• Dojo (1.5.0+)
• Prototype (1.6.1+)
• Yahoo UI Library (2.8.0+)
• DOMAssistant (2.8.0+)
• MooTools (1.3+)
• NWMatcher (1.2.3+)

Then add the following conditional comment:

<!--[if (gte IE 6)&(lte IE 8)]>
  <script type="text/javascript" src="selectivizr.js"></script>
  <noscript><link rel="stylesheet" href="[fallback css]" /></noscript>
<![endif]-->

This adds the selectivizr.js and fallback CSS file to IE6-8 while hiding for other browsers.
