I've seen Tailwind pop up in some of the JAMstack starter kits, and I could have sworn it was some framework of yesteryear that I just missed that was now largely replaced by Bootstrap/Bulma/etc. Now that I've looked at the GitHub, I see v0.1.0 was released on Nov 1 2017! Some of these recent trends in web design really have me scratching my head, but I guess I'm just getting old.
