Change background color of the mobile menu

Hi everyone!

I’ve search for a long time and tried several forum codes that I found, but I haven’t been able to change the background color of the mobile menu of my site.

Right now, you can’t either see the menu icon (the 3 bars), unless you scroll a little bit and the when it appears, the menu item are not visible.

Or if you press the space where it normally is, you see a readable menu, with the black item and white BG. The problem is that if you scroll with the menu open, the item colors change to white and you can’t see them.

My website is: http://www.freedomlifestyleblog.com

I really appreciate all your help to start focusing only in giving great content!
