Fix menu for mobile

[tomkralidis]

The menu should be fixed to be mobile friendly.

Assuming that all of this is done in the default.css, are you utilizing any library or is that just it?

@CarlosMed we are using mini.css as well as default.css for various overriding (see our layout).

Ok cool, I saw the mini there but was unsure. I can help out with the mobile menu and the fork me section if you'd like just assign me the task.
