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.
Discussed SVG use case of including more details as user zooms in, e.g. on a map. While discussing how to solve this, it became clear that while people have some idea of how zooming is interpreted wrt Media Queries, the whole interaction of
resolution and resizing is vastly underdefined and needs work before we can sensibly add related new features.
Discussed possibilities of cross-site attacks via CSS. One case that krit brought up wrt importing shapes was dismissed as Not a Problem. Some others raised by roc & bz might need more thought and discussion.
pointer-events: elements-from-pointsolution that will walk the
elementsFromPoint()chain instead of the ancestor chain (problem is passing events from content to fragmentation container)
::pseudo:pseudocombinations are invalid or match nothing.
