Flex is a new layout mode which provides simple and powerful tools for aligning content and creating complex layouts. Despite it not being an accepted standard from the World Wide Web Consortium (W3C), its popularity in the web design community is growing and browser support is pretty good in everything apart from Internet Explorer < 10 (who expected anything else?). Apparently, the draft of the standard was up for review at the start of September but we haven’t heard any news yet.
