<meta name="assert" content="In this test, the first h4 element would collapse its margin bottom with the resulting (from a margin collapsing with its nested h4 element) of top margin of div#child if only div#child was also a spanning element, which is not: the bottom margin of the first h4 element is 8em wide while the top margin of div#child is only 2em wide (1 column box wide). That is why the bottom margin of the first h4 element should not collapse with the top margin of div#child.">
