Everytime I see Tailwind/Tachyons/Functional CSS at the top of HN I die a little inside. I've said it before and I'll say it again: if you actually like this kind of CSS, you probably don't work on large websites. And when you do, the reason people hate it so much will become abundantly clear to you.

Functional CSS makes for an unscaleable, inconsistent, unmaintainable dumpster fire of styles that is objectively worse than just writing regular CSS.

<sarcasm> But it's convenient, right? So who cares! AirBnB, Facebook, Walmart, Github, and Twitter are all probably wrong anyway. </sarcasm>
