I like the design a lot!
A couple questions, though. Both this post and the readme mention an includes folder, but there isn’t one in the GitHub repo.
Second: looking at the index.html file on the repo, this could *really* benefit from more CSS rules. There’s frankly a lot of white space characters, redundant inline style, etc. that could be done in a much simpler and cleaner way.
I’d be glad to help in any way I can.
