I'm sorry, I really think I'm making this more complicated than it has to be... Very sorry.
I don't necessarily want the standard XF styling, I just want whatever Core came with. I guess I didn't pay attention to the Core banner style.
Now that I look, I think my new style looks bad due to the different border color...
Final question - are my banner setups, as they stand now, the way Core comes? That is what I want.. I will make the new banner look good based on that.
