Thanks for making this PR, apologies for the delay in reviewing it. Joost and I used to do some OSS work as part of our role at Compositional IT but we have both left so haven't had as much time to get on top of these issues. I'll try to find some time soon to get this properly reviewed.

Howdy, I had forgotten to add a line to index.css, that without it much of the more complex tailwind stuff doesn't work. Please see the latest commit. :)
