CSS3 Module Status

The powers that be have decided to split CSS3 into multiple ‘modules’, as the monolithic CSS2 would have become far too unwieldy when expanded to the degree that CSS3 has been. Splitting CSS into modules also allows the W3C to bring those modules up to Recommendation level at different rates.

Following is a table of all the CSS3 modules and their current status. css3.info will be maintaining this table as modules progress through their development stages. The further advanced modules are listed first. No CSS3 module has yet reached Recommendation status.

Illustration of the progress through the development stages made by each of CSS3’s modules.
