I agree with your first sentence, but not with your second.

For my own homepage i did not write a single line of css.

I am very, very bad with CSS and can't wrap my head around it, but tailwind allowed me to create a very pretty, responsive homepage with very high lighthouse scores (bought tailwind UI too).

Congrats, you now know CSS! It sounds like I'm joking but honestly, Tailwind is essentially composable shorthand for CSS with a design system applied. If you grok Tailwind, you understand the concepts of CSS, you just might not know the full names for all the properties and values.

Yes, but when i try to apply this knowledge i fail every time.

I do unterstand the basic ideas behind CSS, but is just cant apply it. Tailwind allowed me to apply it.

If i could, i would prefer to write CSS! After 10 years i have given up though.

That's the thing about Tailwind. It's (almost) the right abstraction.

Personal anecdote, I understood how flexbox works only after using Tailwind for a personal project.

Yes, very true.. But you just don't need to maintain the exploding specificity hell, instead use a declarative workflow, which is significantly easier to reason about.
