Apple plans to bring support for its proposed 3D CSS Transforms—already a W3C working draft—to Snow Leopard, but may be leaving Leopard in the dust. Apple already has support for the proposed standard in WebKit, though currently it is only enabled in Mobile Safari, the browser included on Apple's mobile devices.

Earlier this year, we told you about the rather clever CSS-based, three-dimensional perspective transforms that Apple added to WebKit, extending an earlier two-dimensional concept that enables some rudimentary animation when controlled via JavaScript. The transforms include skewing, scaling, rotating, and positioning of 2D objects within three-dimensional space, and take advantage of 3D hardware acceleration. Using CSS as the basis for defining the transforms makes it relatively easy for Web designers and developers to take advantage of the effects without complicated 3D programming.
