How to add background on Navbar?

[Vibhor]

Hello,

Could any one please guide how do I add a background on the navbar which is currently missing? I'd like to add the one which is serving as category strips (as highlighted in screenshot). I know there's an HTML code to be added, but how and where is the question?
