I use IE7.js but it doesn't have CSS3 support. I use jQuery always in my projects. What is the best lightweight way to give all CSS3 selectors and properties support to IE 6,7,8? I'm not asking for HTML5 support only asking to give CSS3 support in as much as light on performance way.

How to give CSS3 support to IE?

Try keith clarks IE CSS3 pseudo selector emulator: http://www.keithclark.co.uk/labs/ie-css3/

I haven't personally used it but it manually parses your css file and adapts it for ie-browsers.

A downside is you're relying on js for css functionality..

the IE7.js project linked in the question has recently added IE9.js. This brings more CSS3 selector support to legacy IE.
