And @Lorne-Kates False!
Can I use... Support tables for HTML5, CSS3, etc
Sure I'll just click through on all of those.
"All of those"? It's a link directly to the table for CSS Animations. And it's almost entirely green which means supported. The vast majority of browsers support Animations and Transitions, and they are consistent enough to cover color-fade-on-hover and even image carousels without any issue i've seen thus far.
