Menu breaks when you zoom in and out
So, my category menu breaks every time I zoom in or out. I am using responsive design, and everything is fine when you just resize the browser window. It's when you use the zoom feature that it breaks. When I say "breaks", I mean the "Random Things" button drops under the menu bar.
I tried changing the padding around the buttons, but that leaves a gap at the end of the menu.
I can't seem to figure this out.
Any help would be greatly appreciated.
