I have a phaser project within a container and I can't add a border radius to the container for some reason. Here's the code.

You can't apply border radius to IFrame elements, but you can cheat and apply it to the container. Not sure how effective this is cross-browser though: http://codepen.io/lewster32/pen/AEkca
