Acid 3 100/100, great and all however it's Presto 2.3 that will had a vector graphics library named Vega. In short the version after Opera 10 (10.2, 10.5, or whatever) will finally see some decent CSS3 support. Selectors can effectively be emulated by a serverside language however properties can not.
