Some problems with the menu formatting. First of all, the top of the submenu is set to 1.5em, which means it partially obscures the main navigation bar. It’s not that apparent by default, because the background of the menu items is transparent, but I added some CSS to the hover state of the submenu items to make it easier for the user to see what menu item was being selected, and you could see how the submenu overlaps the main menu items.

Second, the submenu on mobile screen sizes is positioned really poorly. On a tablet, it floats off to the left, and on a cell phone, it overlaps the main menu, and because the menu item backgrounds are transparent, the menu text gets mixed in with the submenu text.
