Created attachment 708738 [details] properWithImproper.png User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.7; rv:21.0) Gecko/20130131 Firefox/21.0 Build ID: 20130131031009 Steps to reproduce: Attempting to use the shorthand "flex-flow" property to list elements in a row and then wrap them as listed in the documentation https://developer.mozilla.org/en-US/docs/CSS/flex-flow Doesn't seem that the shorthand "flex-flow" with the "flex-wrap" property is recognized in 21.0a1. Using the associated prefix in Opera & Webkit gives proper results: http://jsfiddle.net/M7yLn/1/ Actual results: The elements in the row overflow the parent container and do not wrap to create multiple rows. Expected results: The elements should wrap to create multiple rows within the parent container as shown in Example 4 at http://dev.w3.org/csswg/css3-flexbox/#flex-flow-property
Ah yea missed footnote on the doc, need to add "wrap" to the tag for searching. Wasn't thinking "multi-line" ha.
