When using a divider, put an arrow/triangle in the centre of it.
If you want to separate two sections but keep some connection between the two of them, you can add an arrow/triangle to the divider, pointing at the next section of content. This might help if you want to put a divider between a fixed area, and an area that expands to show content, but still want to connect them in some way.
The dividing line here is unbroken, so it's still a strong visual divide between two areas of content. There's a good chance users will assume the two areas are separate, even with the arrow.
