Although CSS 3 is there, it's not good to use now [atleast in my opinion], where most of the users will not be able to see it. So I just want to know if there is a JS library, which forces css3 on browsers? Ideally, it should scan the CSS for CSS3 code, and just implement it. No dependancy of certain classes etc. Atleast, these features; Border Image Rounded Border Box Shadow Text Shadow RGBA (so opacity included) are necessary. I wouldn't care if it takes 10 seconds to process JS & has 100 kb weight. Any suggestions?
