OK, so I sat down with some people at Microsoft to go over this, and it seems we have a problem: block-axis baselines aren't really a thing that should exist for a box. The problem is illustrated by this example: Imagine a grid with three items in a column: 1. First item is horizontal-tb 2. Second item is vertical-lr 3. Third item is vertical-rl If we try to baseline-align the first column, which baseline do we use for the horizontal-tb item? The vertical-lr and vertical-rl items are in independent baseline-sharing groups: their first baselines are on the left and right sides of the column, respectively. But the horizontal-tb item has no reasonable way to choose left or right as corresponding to "first". So my conclusion is that we should remove the concept of block-axis baselines. A grid column might have baseline alignment along its block axis among items with orthogonal flows, but it does not propagate that up to the grid container. -- GitHub Notification of comment by fantasai Please view or discuss this issue at https://github.com/w3c/csswg-drafts/issues/197#issuecomment-239996012 using your GitHub accountReceived on Tuesday, 16 August 2016 04:06:12 UTC
