Do you want to know how the CSS WG works? Fantasai has written about:csswg, An Inside View of the CSS Working Group at W3C.
The WG looked at the handful of remaining test cases for CSS 2.1
that don’t have two passes yet. Some are no doubt invalid, some will
need careful study at the ftf.
The upcoming ftf will have some extra guests to talk about layout grids and non-rectangular flows. The one after
that should have a forum right before or after it to meet with Japanese
designers and companies.
