This isn't a question, I'm attaching a graphic of a module from my online course. It shows a lay-out designed to break-up the monotony of seeing just a bunch of hotlinks, plus it segments course material with some visual clarity.
I’m posting the graphic in case others might find the layout of interest.
Unfortunately, the indentation doesn’t work on a mobile application (at least not that I can tell), it only works on desktop PCs. Yet I'm happy with the overall effect on a computer screen.
The black band was created using an ASCII code though I forget which one.
