To your example, recent Bootstrap has a mix of component and utility classes that lets you do both "alert-danger mx-0" or whatever.

I also avoids the giant size of Tailwind classes that requires that elaborate build/reduction process. You can just include Bootstrap from a CDN or whatever.

There's also daisyUI, which is sort of like Tailwind + Bootstrap: component-based, but made with Tailwind. Cuts down on the tag soup pretty nicely.

Yes DaisyUI is nice. Ironically, it convinced us not to move from Bootstrap, because we realized its components were almost 1:1 with Bootstrap. And that we actually don't want the infinite styling options that Tailwind offers, so that devs mostly use design system components. At that point, who cares where/what the CSS is?
