margin-collapsing should not happen in this context, see bug 616722 comment 8
Summary: Margin-collapsing broken with parent with columns and border → margin-top of first-child of a multi-column element having border-top not rendered
Hello, When I try the test in URL field, I get a 10em (160px) top margin above "asdf". I am using Firefox 22.0, buildID 20130620121849, Linux KDE 4.10.4, i686 (32bits), kernel version 3.8.0-25-generic. WORKSFORME I have verified with 1 other test ( eg http://test.csswg.org/suites/css3-multicol/nightly-unstable/html4/multicol-margin-001.htm you must manually insert the following declarations -moz-column-count: 3; -moz-column-gap: 0px; into the inspector style of web developer tools and then compare with its reference file: http://test.csswg.org/suites/css3-multicol/nightly-unstable/html4/reference/multicol-margin-ref.htm ) where the first block child of a multi-column element has a margin-top and it is rendered as expected.
