It looks like only Apple has hooked up WebKit animation to an underlying Core Animation-equivalent layer in the OS which uses the GPU for most of the hard work.

Not sure if Google is really motivated to do this kind of system-specific work in Chrome beyond the basic port.
- swannodette 16y agoI would argue that they should be. CSS is well understood by designers/programmers and doing animations all in JS is error prone and off course a CPU hog. Hardware acceleration is particularly important when you're talking about devices with underpowered CPUs (Android). On my iPad/iPhone CSS animations outperform JS animations by a ridiculous margin.
- cpr 16y agoJust to clarify, they do have the CSS-based animations, since they're WebKit-based, but they're just not hooked up to an underlying hardware-based implementation.
