Hello all, it's me again.
Is it possible to change the size(s) of either the main content area or the header so that the header image goes all the way to the edges on the left and right sides? I'm not sure if I'm calling the sides/edges by the proper name. What I want is the edges of my header to meet the black background without that little bit of off-white space between the header edge and the background. (I may not keep that header, but having the header meet the background is something I would like to use on future headers as well.)
If it's not possible that's fine, I just wanted to find out.
