CSS3 Introduction
CSS3 is fully backward compatible, so you don't have to change existing designs.
CSS3 Module
CSS3 is split into "modules". The old specification has been broken into smaller pieces, and new ones have been added.
Some of the most important CSS3 modules are as follows:
- Selectors
- box model
- Background and border
- Text Effects
- 2D/3DConversion
- Animation
- Multi-column Layout
- User Interface
CSS3 Suggestions
The W3C CSS3 specification is still under development.
However, new browsers already support CSS3 properties.
