Nice! I still think making your own utility classes is far better in many ways than using Tailwind, but that isn’t the point of this learning project. Congrats!
I just removed tailwind from a big project (~20k lines) and it was so easy while improving DX, bundle size, etc. I used to love tailwind but that was just me not knowing enough CSS.
that works fine for solo projects but falls apart in dynamic team environments. much better to have one set of utilities to learn once and use everywhere, i think, than to have to read through hundreds or thousands of lines of CSS scattered across multiple files to figure out what is going on.
