I want something very simple I think...
2 rows, 2 columns, left column spans both rows, right upper should be auto height but 50% max (that's the problem), right lower should take up the rest.
When I do grid-template-rows: auto 1fr; the first row is only as big as it needs to, but when I try minmax(0,50%) 1fr; (or any other combination of units I can think of) the first row is always 50%. Why? How can I get the auto height behavior of the first row but with 50% max?
