100% this. People have all of these highfalutin arguments about tailwind being the wrong abstraction/non idiomatic etc. But, as someone who writes a lot of CSS—not having to jump back and forth between a CSS file and a HTML file is a game changer. CSS files are just another thing to maintain, and a painful one at that, since CSS is mostly organized relatively arbitrarily. This is why Tailwind won; reducing the surface that developers have to maintain is a big deal.

There are simply so many decisions when choosing how to implement CSS in a project—where should we put the files, should they be component based or global, what preprocessor if any, etc etc. With Tailwind, you don't have to worry about any of that.
