Yes, assuming I get some time on it, a short book (75ish pages) on Tailwind will be going into beta the end of January.
As far as front end as a whole, I basically have no idea. Eventually somebody is going to have to figure out a way to make the JS ecosystem less complex, but I’ve been saying that for years, and it just keeps getting more complex, so who knows?
I was very skeptical about Tailwind until I used it on a project. What I like about it most is how easy it is to experiment with it and how relatively easy it is to predict the effects of a change relative to “normal” CSS on a large project. I also like the idea of depending on your code structure to manage CSS duplication, but I do think that raises the possibility of a team getting very tangled in long Tailwind strings that are duplicated mysteriously throughout the code.
