Whenever the first inline (not floating/absolute) child block has a margin-top, it is applied to the parent block instead of the child block. Reproducible: Always Steps to Reproduce: 1. Create a <div> or other block-level region 2. Create another <div>, <p> or block level region inside of the first 3. Assign a margin-top (via margin-top or margin in CSS) to the second block region. Actual Results: The top margin is applied to the outer div, not the inner div. This does not occur on any other margins, just margin-top. Expected Results: The inner div would have a margin at the top. This seems to happen on any block regions though I haven't tested them all. This causes the bug: <div> <div style="margin-top: 10px;">Test</div> </div> This is a "work around" that always works: <div> <div style="padding-top: 10px;"><div>Test</div></div> </div> Found in: WinXP x64 SP1 (FF v188.8.131.52, FF v184.108.40.206, Minefield v3.0a3pre 2007-03-09 build) WinXP Pro SP2 (FF v220.127.116.11, FF v18.104.22.168)
