The CSS Working Group and SVG Working Group today jointly published a First Public Working Draft of Web Animations 1.0, which defines a model for synchronization and timing of changes to the presentation of a Web page. This specification also defines an application programming interface for interacting with this model and it is expected that further specifications will define declarative means for exposing these features. The Web Animations model aims at two broad areas of application: User interface effects, and Storytelling and visualisation.
The two groups also updated today Compositing and Blending Level 1. Compositing describes how shapes of different elements are combined into a single image.
