<title>CSS Grid: percentage block-size transferred through a row subgrid into the grid's intrinsic inline-size</title>
<link rel="match" href="../../reference/ref-filled-green-100px-square-only.html">
<meta name="assert" content="An intrinsically-sized grid with a definite row and an auto column sizes its column from an aspect-ratio grandchild with a percentage block-size that lives inside a row subgrid: the subgrid is stretched to the row, so the percentage resolves against it.">
<p>Test passes if there is a filled green square.</p>
