Thanks, it's a very good work.
I've changed these css to get a better navigation on Android HTC mobile device
here are the two lines i've changed :
l.429 .mobile-nav{display:none;width:50%;position:absolute;line-height:1;padding:0 30px;font-size:30px;text-decoration:none;}
l.704 .sidebar .social{margin-top:40px;padding-top:15px;border-top:1px solid #ccc;}
The test page, try it on 320px width
