First Public Working Draft: CSS Easing Functions Level 2

The CSS Working Group has published a First Public Working Draft of CSS Easing Functions Level 2. This CSS module describes a way for authors to define a transformation that controls the rate of change of some value. Applied to animations, such transformations 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. Level 2 adds more sophisticated functions for custom easing curves.
