It's really for the React generation. People used to embedding the code, markup and style all in one file.
I've tried multiple times to use it, but I always end up using something like bootstrap. Funnily enough, I paid for tailwindui and take the styles and reproduce them in bootstrap css.
Bootstrap community seems to have given up. They only want to sell templates. The default is ugly. Sometimes I think about going back to bootstrap 2.
If you're using React, check out Material UI. I was a big fan of Bootstrap, but I didn't like that there was still so much for me to build. MUI comes with components for things like user avatars out of the box. But it doesn't get in the way at all either, it's very customizable at the theme and the component level (I'm using it with styled components, and I love not having to come up with class names for everything). I've also tried Antd and it's impossible to customize.
