This is a page from the Cascading Style Sheets Working Group Blog. Some other places to find information are the “current work” page, the www-style mailing list, the Future of CSS syndicator, and the issue list on Github.
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.
We reviewed Steve’s email and also an internal generic “transform” proposal from Hyatt (which Hyatt will hopefully post to www-style at some point), spending most of the day discussing exactly how “rotation” would fit into the CSS layout model.
Rotation is still at a very experimental stage in CSS, so the following are not final decisions.
width: auto
on a rotated element means use the available width before rotation.width: max-intrinsic; rotate: rotate-to-fit-keyword
enables the case where we shrinkwrap around the text to find its width and pick the smallest angle that will make that block fit.width: shrinkwrap
uses the available space after rotation, starting with one line and making the block taller and narrower as more content comes in, until it reaches its minimum content width (or min-width).
