He wrote "learn your CSS conventions" which implies that every team and every project will have a different set of conventions. Hidden inside that statement is the fact that he just accepted that Tailwind should be THE CSS convention, something I personally disagree with but to each their own.
No. Tailwind is a way of writing css, not a convention. By “your” convention I’m referring to the problems with the cascade, ie naming classes and so on. I’m not saying tailwind is the only other way. There are many ways to write CSS but doing it with something bespoke for your situation is usually a bad idea.
