Hello, [RC6] http://test.csswg.org/suites/css2.1/20110323/html4/abspos-010.htm [nightly-unstable] http://test.csswg.org/suites/css2.1/nightly-unstable/html4/abspos-010.htm If you examine this test with various browsers, you'll notice a difference of rendering (height of green area): Opera 12.02, Chrome 21.0.1180.89, Safari 5.1.7, Konqueror 4.9.0 all render a 48px wide by 48px tall green square. Firefox 15.0 and IE8 render a 48px wide by 64px tall green rectangle. The difference is due to how vertical margins are supposed to be rendered: the 2em margin-top of the abs. pos. table (.fixed) should *not* collapse with margin-bottom of <p>. So, Firefox 15.0 and IE8 are correct. So, I revisited [RC6] http://test.csswg.org/suites/css2.1/20110323/html4/margin-collapse-012.htm [nightly-unstable] http://test.csswg.org/suites/css2.1/nightly-unstable/html4/margin-collapse-012.htm and noticed that a few more tests could be submitted to better cover possibilities: With margin-bottom: http://test.csswg.org/source/contributors/gtalbot/submitted/margin-collapse-012a.xht With a collapsed-through element: http://test.csswg.org/source/contributors/gtalbot/submitted/margin-collapse-012b.xht With with margin-top (with an abs. pos. table): http://test.csswg.org/source/contributors/gtalbot/submitted/margin-collapse-012c.xht With margin-bottom (with an abs. pos. table): http://test.csswg.org/source/contributors/gtalbot/submitted/margin-collapse-012d.xht With a collapsed-through element (with an abs. pos. table): http://test.csswg.org/source/contributors/gtalbot/submitted/margin-collapse-012e.xht abspos-010 test seems wrong too because table-layout: fixed does not apply if (at minimum) width of table is not specified... and the test uses a table that has 1 single row which has 1 single cell.. Right now, I think this test is not good, not trustworthy because it does not achieve the original goal/intent of the test. Such test, as designed, does not demonstrate the goal of the test.
