i’m not a frontend engineer so don’t know the difference between text- and font- without looking but that’s another good example of why frameworks are great: 6px is an explicit size, where md, 2xl, etc are all relative… per project you can decide what those sizes are and everything just falls into place… you rarely really care what the size is in pixels; mostly you only care about sizes relative to other parts of the UI… so again, people joining on a project don’t need to memorise magic numbers, because they just know without needing to guess what the size suffixes are
i’ve only recently started to use tailwind (originally i saw no point, pretty much for the reasons you’re stating: why use classes like that when you can just use styles on the element and we know that’s bad) but since i embraced it i’ve started writing quality components much much faster… especially for layout like flexbox and grid it just flows really nicely, and i really don’t find that it feels like i’m repeating myself at all (partly because “repeating yourself” should be avoided by simply using components these days: CSS is an over-complicated and ill-fitting solution to the problem of styling in modern UIs)
(okay i looked up text- and font-: text is size, font is weight… which tracks with my understanding of the other parts of tailwind and the way type is handled in software generally… i think there are no good options here)
