Isuue with sub-menus

[awlang]

I've been trying to get the sub-menus to change background colour when hovering over but can't seem to do it. The preview and demo Skeloton site does have menus that do this, but my site doesn't when using this theme. Is there an easy fix please?

Dear @awlang, please, contact me in some way (for example via iikuzmychov@gmail.com). I want to discuss one thing with you related to your GitHub account username. Can't find any other way to contact you except this old issue comment section.
