Thanks, but that seems to fix something else. :)
I still see the social bookmark section halfway hidden behind the mobile menu. Pls try the home page with a width around 1000px.

Thanks. Two more things:
Is it possible to add an Alt Text or change the mouse over behaviour?
Is it possible to add more icons? I tried so far and uploaded another zip file with some more fontello icons, but it does not show up in the import section.

Sure. Next to the main menu, at the far right :)
