I wonder what the future of code-splitting with Tailwind will be. With JIT and a large web app, it's easy to ship a massive CSS file even if 90% of the rules are unused on 90% of the pages.
The Tailwind website is only 36.9kB of CSS and it likely includes more classes than any other Tailwind site on the internet by virtue of the fact that it has to provide visual demos for so many of the classes. I don't think 36.9kB is massive personally, it's much smaller than the CSS of almost every website I've checked.
