Description Darby Dixon III 2023-04-27 09:56:09 PDT
Element with container-type: inline-size, display: grid, and auto-fit grid-template-columns collapses grid column widths to 0

Minimal error case:


Summary: I have an element set to display: grid, with auto-fit columns. This works as expected.

As soon as I add container-type: inline-size, the grid width (column widths) collapse to 0 width. Switching to auto-fill columns, however, the columns work as expected.

While I didn't reproduce here, setting container-type to size appears to also collapse the height of the grid rows to 0.

I've noted mac apple silicon / macos above, but I've reports of this error on an iphone as well.

Issue is still present. Can be solved by moving container query to grid's wrapper element (which can cause bad semantics).
The buggy Safari behavior works fine on Chrome and Firefox.
It would be great if resolved soon.
