Apologies - I'm developing on firefox aurora and haven't had a chance to test it on older versions yet. I honestly wasn't prepared for a HN submission but some more cross browser testing and mobile testing are very high on my todo list. This is my first project where I've developed with an IE10+ only policy, which is actually really nice because of flex box, but it's easy to accidentally break other browsers if you miss a single prefix.
