AFAICT, Tailwind is largely (not entirely) a different, shorter syntax for writing inline styles. (E.g., "class: 'bg-white'" = "style: 'background-color: white'".)
If you've rejected structural CSS to begin with, I sort of get the point that it saves a lot of typing; otherwise I don't see how it helps all that much over SASS or just modern plain CSS.
Tailwind is a dirty hack, normally you are supposed to declare a class, which you apply to items of the same concept. This is the cause for CSS to exist.
Front devs got lazy, and started writing for each element, position: absolute; left:3px, top:6px, color:red;...
You could write
<font color="red">Hello</font> this would be similar "cleanliness"
If you're a senior CSS developer you will invariably reach a point of using "object oriented CSS" which is where you combine classes to an effect.
At that point you're not far off Tailwind. TW just took it all the way.
