Hello,

Can i please see a link of the page? Most probably there is a css class missing or incorrect in your code. I need to check the page so i can give you the right code to add.
Let us know.

Best regards!

Hello,

Do you want to give color to only the menu bar? If so, edit the code to this:
.header_10 .full_nav_menu { background: rgba(0, 0, 0, 0.2) !important; }

If you want to include the entire header, logo too. Then add this code too:

.header_wrapper {
    background: rgba(0, 0, 0, 0.2) !important;
}

Result screenshot.

Best regards!
