It’s more about cognitive load, and abstraction level. If you’re trying to make an object spin, it’s much easier to use the tailwind class than it is to remember css keyframes.

Sure, when debugging a complex issue, it’s worth knowing the low-level, but CSS is not a great abstraction for day-to-day work.

You’re right that it’s not much more than a css in js library, but I’ve found myself pleasantly surprised at how efficient I am using it, despite also having years of css experience.

Things like remembering what the flex syntax is, or coming up with a padding system or a colour scheme become very very easy.

I think the editor tooling for tailwind is where most of the benefit comes from.

I also prefer the syntax over direct css in js systems. It’s less characters, which means it’s easier to parse.

Give it a try, you might be surprised!

Can you suggest a best place to learn CSS in-depth, from first principles? (as opposed to, say, simple tutorials)
