Prefix free lets you use only unprefixed CSS properties everywhere. It works behind the scenes, adding the current browser’s prefix to any CSS code. Processes every stylesheet in <link> or <style> elements and adds a vendor prefix where needed. Just include prefixfree.js anywhere in your page. It is recommended to put it right after the stylesheets, to minimize FOUC.

The target browser support is IE9+, Opera 10+, Firefox 3.5+, Safari 4+ and Chrome on desktop and Mobile Safari, Android browser, Chrome and Opera Mobile on mobile.
