I’m not sure where the right place is to give this feedback. I was going to recommend the beta course to a friend so I decided to try it out.
In general it looks great! Congratulations.
One thing I didn’t like is the lack of visual distinction between code and instructions. For example:
I would suggest making the instruction area have a different background colour. Otherwise it’s just a whole lot of gray. I know that the instructions are in a serif font and the code is in a mono font, but to me that isn’t enough to separate. Having the instructions embedded in the code is probably a good thing, but I’d make it more distinct.
Perhaps like this:
If this isn’t the correct place to give feedback, please let me know.
