Nebula theme question
I'm not sure if I'm posting this in the right place, and I'm sure this is an easy fix, but I can't seem to figure out how to put a background image on the header/logo area in the nebula theme.
I can upload the logo, customize the CSS file etc, but I just can't seem to get a background image on the header area as a whole..
I'd be extremely grateful for any help with this! Thank you in advance.
