Prefix free: Break free from CSS vendor prefix hell!
-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, only when it’s needed. 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. If it doesn’t work in any of those, it’s a bug so please report it. Just before you do, please make sure that it’s not because the browser doesn’t support a CSS3 feature at all, even with a prefix. In older browsers like IE8, nothing will break, just properties won’t get prefixed. Test the prefixing that -prefix-free would do for this browser, by writing some CSS below: Properties/values etc that already have a prefix won’t be altered. It’s not ideal, but it’s a solution, until a more intuitive way to deal with these cases is added in -prefix-free. Please note that in unsupported browsers like IE8, no such class will be added. Firefox (and IE?)
