Thnk you, Anders, for taking the time to reply. It’s much appreciated. As you can tell, I’m a complete newb when it comes to coding. However, I searched on the web and found instructions for creating a child theme, which I have managed to do. Would you know where I could now look to find the code to display both the logo and the tagline?
Rowling is a great theme, by the way. I looked at hundreds (believe me, I’m not exaggerating) and this was by far the most elegant and streamlined for a magazine-style blog.
I have actually found what I needed to do. It is the accent color that needed to be changed.
