Anyone want to help me debug a little experiment I’m working on. I want to use flexbox/multicolumn layout to get a layout similar to what you see in many Windows 8 news app, where the article(s) are in fixed width columns, with a dynamic number of columns depending on the length of the article, that scroll off to the right.
So I whipped up this [jsfiddle](http://jsfiddle.net/ySaH7/5/) or [CodePen](http://codepen.io/anon/pen/tcGuF) but flexbox and the columns don’t seem to be working together well. In Firefox, it only shows one column of each, and I can’t even tell what’s going on in webkit.
What am I screwing up?
(I looked and in Windows 8 html5 apps they seem to use grid layout, but I can’t do that since it’s IE only)
