A CodePen by Matt Litherland. Ultimate Pop-Out Menu - I built this navigation strictly for a Mobile Web App, it utilises hardware acceleration and is cross device compatible. I have testest on iPhone4+, Nexus 4, Blackberry Z10. It also works beautifully on Webkit Browsers, Chrome & Safari, has been tested in Firefox. I have not tested in IE as it was never intended for web.

Viewport Fixes:
When testing on your mobile, you will notice the viewport is fixed on all orientations, with scrolling overflow working as you would expect.
