Random grid gotcha that drove me crazy some time ago: due to browser bugs we can't use elements with percentage widths or heights as grid items. The grid cell dimensions get blown out to the ones of the original image. Seen in both Firefox and Chromium. Relevant FF bug is probably https://bugzilla.mozilla.org/show_bug.cgi?id=1857365 ' grid item with percentage height, "width: auto", "grid-template-columns: auto", and…

so if the img has a specific size set in width and height attributes or via css, and that size is not percentile or auto, the problem doesn't exist? I'm just confused by the "original image's width".

Yeah this is a good callout. My understanding is that display: contents is not meant to impact the accessibility tree but there is a long and ongoing history of browser bugs that make me not want to use it for elements that have an accessible role

From my testing, as far as I've been able to tell it no longer has any impact on accessibility. The element itself does not appear in the tree, this makes sense display:contents is non-interactive. But all of the children correctly appear in the accessibility tree as if they did not have that shared parent element. But I am by no means an expert at operating screen readers, do you know of any specific issues with it?
