Yet another #rwd navigation solution

Let's have a bit of fun eh?

On the morning of Saturday 3rd of November 2012 I was thinking about Malarkey's navigation system he uses for his site Stuff & Nonsense . Where it fades in and his icon flies down when clicking the navicon . I was wondering about a flying in and out navigation 'box' when clicking the navicon and how that'd look 'really cool'. Here it is.

Caveat

For some reason the navigation doesn't kick in on codepen in the editor mode when at a narrow viewport

It uses zepto.js which is a small JS package thing than jQuery. Of course it's interchangeable with jQuery if needed.

The navigation stays hidden if it's hidden by the 'user' at a narrow viewport when you then resize the browser
