Ok, I found it, but adding the lines of code did not work to make the borders show up on the widgets or to make the header larger. Nothing actually changed, even when I made it 1000 instead of 200.
Thanks so much Yigit. (Sorry for my delayed response. I’m laid up with a ruptured disc in my back ;)).
So I’m trying to do these things one at a time. I searched everywhere to find the “Quick CSS” but could not find it. If I update the regular “CSS Stylesheet Editor” and add that code to the line, nothing happens. Any advice?
