User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:2.0b7) Gecko/20100101 Firefox/4.0b7 Build Identifier: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:2.0b7) Gecko/20100101 Firefox/4.0b7 When using flexbox (-moz-box styles) and HTML5 doctype, empty <div> elements used in the composition of an element creates a layout issue. The flexbox element is misaligned with respect to the top of the parent element. A 16px top margin gets implicitly inserted between parent and child element. The workaround is to either remove the DOCTYPE header or insert non-breaking spaces into the empty div elements. Also repros on Firefox 3.6. While the margin issue is visible, it's not visible to Firebug. (Firebug shows the offsets, margins, padding, and sizes of inner and outer div elements as they should be). Does not repro on Chrome 8.0.552.224 I wrote a very simple example page here that demonstrates the problem. http://www.harstinecottage.com/ffissue/index.htm Reproducible: Always Steps to Reproduce: 1. Create an outer div of any size (say 300x300) 2. Create an inner div to use width:100% height:100% display:-moz-box -moz-box-orient:horizontal. 3. Create 2 child elements within the inner div. One has a fixed width, the other gets stretched via -moz-box-flex:1 style. 4. Do not insert any content within the divs created above other than the nested child divs. See sample page on: http://www.harstinecottage.com/ffissue/index.htm Actual Results: Total outer div size is 16px larger than it should be. (300x316 in this example). Child element is correct size, but shifted down within parent. Hence, it appears there's a 16px margin. Expected Results: No margin added. Workarounds should not have to be applied.
