No, that's not true; a 2023 book giving advice like "don't use borders" is definitely not in any way a seminal source of "good design".
Besides, I'm not saying I think it's a fundamentally bad design, I'm saying those voices are drowned out by the people on-board with it - for a great example, consider how you just came into the conversation, squished the nuance I was discussing, and gave hyperbolic praise to their book just because you like their tool.
Millions of engineers are now more empowered to make design decisions - and given more convenient tools. The price - ignoring how CSS was designed to work, unreadable mess of classes in the markup, a bootstrap-like cookie cut approach to everything, and yes, the color purple.
The book included some useful rules for people new to interaction design.
These can be applied without the use of tailwindcss.
Use of the framework tailwindcss has nothing to do with the book.
The framework itself goes against the intended use of css. It ignores the power of the cascade and leads to a pile of incomprehensible css repeated over and over again.
It is convenient and unreadable at the same time.
Handy if you don’t want to learn css and use it properly and completely unacceptable if you do.
