This was panel session. They talked about the state of CSS, where we are at, what is pending, what we can look forward to.
Also discussed: the support for CSS4 specifications, what we can expect in the future and how it will be useful for web developers and designers.
Features to look forward to:
CSS layout capabilities
Snapshots – summarizes the modules stabilized
Tools to Separate content and style – want to be able to change content or style sheet without worrying about the other
How can you use these features for legacy browsers.
A CSS support spec will help to use these new things more easily, that is in progress.
