Introduction to CSS3


CSS3 is fully backward compatible, so you don't have to change your existing design.


CSS3 Modules

CSS3 is split into "modules". The old specification has been split into smaller pieces, and new ones have been added.

Some of the most important CSS3 modules are as follows:

  • Selector

  • box model

  • backgrounds and borders

  • text effects

  • 2D/3D conversion

  • animation

  • Multi-column layout

  • User Interface


CSS3 Recommendations

The W3C's CSS3 specification is still under development.

However, new browsers now support CSS3 properties.
