The CSS Working Group has published two First Public Working Drafts today:
- CSS Timing Functions Level 1, a module that describes a way for authors to define a transformation to be applied to the time of an animation. This can be used to produce animations that mimic physical phenomena such as momentum or to cause the animation to move in discrete steps producing robot-like movement.
- CSS Containment Module Level 1, a module which describes the ‘contain’ property, which indicates that the element’s subtree is independent of the rest of the page. This enables heavy optimizations by user agents when used well.
