The Cascading Style Sheets (CSS) Working Group and Technical Architecture Group (TAG) have published four Working Drafts:
- CSS Properties and Values API Level 1: This CSS module defines an API for registering new CSS properties. Properties registered using this API are provided with a parse syntax that defines a type, inheritance behaviour, and an initial value.
- CSS Painting API Level 1: The paint stage of CSS is responsible for painting the background, content and highlight of a box based on that box’s geometry (as generated by the layout stage) and computed style. This specification describes an API which allows developers to paint a part of a box in response to geometry/computed style changes with an additional function.
