I'm having some issues with nested flexbox in Safari, IE11 & IE10. The panels are supposed to be side-by-side (50% width), and have varying amounts of content in them. The <cite>
element should be anchored to the bottom of the panel and each panel should be the same height.
Here's a codepen to illustrate: http://codepen.io/anon/pen/BKNRBY
This works fine in Chrome / Firefox, but in Safari, IE10 and IE11, the panels don't stretch vertically to contain their content.
Can anyone offer any advice?
