Navigation on mobile - background color missing

Hi there,

I have an issue with a client website where the mobile nav menu that opens from a hamburger menu has no color background. The website link is here:

The code I have tried out to fix the issue is below, however nothing happened.

.sqs-mobile-nav-open a .icon-hamburger {
    color: #F4F1EA; !important;
}

Thanks in advance for any help!

Omg I completely missed that! Thanks so much 😅 @LoftyDevsbyWidleStudioLLP
