Call for Participation in CSS4 Community Group

The CSS4 Community Group has been launched:

A group to debate and define CSS4.

This WICG group is a place to work out the details.

In order to join the group, you will need a W3C account. Please note, however, that W3C Membership is not required to join a Community Group.

The group must now choose a chair. Read more about how to get started in a new group and good practice for running a group.
