This article is outdated and no longer accurate. Find up-to-date information about flexbox at HTML5 Please. Yet Another Note (2012-05-13): It might be obvious that the flexbox spec is changing often, but a kind commenter suggested I add a note here regarding the fact that in the spec, the flex() function has been replaced by the `flex` property, which makes plenty of stuff in this article obsolete
