The advantage of Tailwind [1] is very subtle over the short term (such as not having to constantly context switch between HTML & CSS files), but dramatically impactful over the long term.
Both in terms of time-savings, as well as code quality and ability to work with others quickly.
It really is something that you must earnestly try to gain an appreciation for.
My initial reaction was the same as the authors when I first came across it. Actually using it on a real life project changed my mind.
