Website menus - Problem on mobile site

[J9MM0]

Hi all,
Could anybody point me in the right direction to change the background for the main menu on the mobile site?
It works fine on the main site ref: www.selfbuildplans.co.uk but on the mobile site the menu has a white background which blends with the white text and therefore shows nothing. I have found the background and text colours for the main site i just need help with the white background for the mobile site.
Thanks.

It's difficult to answer all of your questions, so I recommend to use google Chrome DEVtool.

https://developers.google.com/web/tools/chrome-devtools

It will help you to find the solution.

This time, you can change the background color by editing or overriding stylesheet.css line 627.
At first, you should test on the DEV tool and then, change your css file.
