I ran across this video, worked out the code and had to share! This will really be helpful in building simpler navigation menus for mobile websites.

Heres the Video

I only added a few things
-a document ready function for the jquery to work for me
-a meta tag to remove the default zoom on a mobile phone (so it doesnt shrink your design)
-the nav menu icon (?) that he left off in the video
-different colors
