Hĺkon, [test] http://test.csswg.org/source/contributors/opera/submitted/multicol/multicol-span-all-margin-nested-003.xht [reftest] http://test.csswg.org/source/contributors/opera/submitted/multicol/multicol-span-all-margin-nested-3-ref.xht The reftest claims that the black rectangular area should be 22em wide but, after a long examination of related specs, I can not reach such conclusion and, more important, I can not reach any conclusion about the width of the rectangular area of/in the test. There is also no consensus and no unanimity among user agents with regards to the width of the black rectangular area. I wanted to propose a modified test based on it but I can not. When available width is not provided, then, right now, according to the status of the spec (CR[1] or editor draft), anything - or nothing "solid" - can happen. In order to establish the used width of column boxes, we need a way to figure out U (used width of multi-column element) before entering §3.4 Pseudo-algorithm [2] and how such U is supposed to be calculated, defined is up to Basic Box Model [CSS3BOX] or the Intrinsic & Extrinsic Sizing Module [CSS3-SIZING]) and even there, after reading §4.2 [3] and §4.5 [4] of css3-sizing, things are still not clear. So, I can not approve multicol-span-all-margin-nested-003 test right now.
