To start with, I'm extremely new to CSS but, for the most part, I've been able to get the layout to do what I want with all the help from here. There is only one single object I can't figure out how to change because all my educated attempts at guessing what it is seem to be failing. What I want to change is the color of this little divider here.
I thought it should be something with the prevnext, but now I'm not so sure. I really have no idea. Would someone be so kind as to point me in the right direction of where to find this information or otherwise what tiny clip of CSS I need to use to change it?
