10up, one of the bigger WordPress agencies, has released Flexbox support for IE8 and 9 that also happens to be GPL.

The support is included in flexbox.js, and can be used in any project regardless of whether or not it is built on top of WordPress. There’s a complete guide to Flexbox via CSS Tricks, and you can find the JavaScript on 10up’s GitHub.

If you’re forced to support older browsers, this script will allow you to create the same kind of layout you have for the newer, shinier ones.
