Grids all the way down
summary
Two years after Grid Layout ships the spec adds subgrid to let nested components share parent tracks so captions and card internals line up without breaking source order; demos use CSS Grid with minmax for resilient row heights and show display: contents removing wrapper boxes but currently breaking accessibility in many browsers. Firefox is implementing subgrid in Nightly behind a flag, Chromium has an open bug to star, and practical advice is to use feature queries, test with keyboard/tab tools, and file issues with concrete examples.
