Correct.

I like the "Controlling File Size" of the Tailwind CSS project: https://tailwindcss.com/docs/controlling-file-size

They DO tell developers to remove unused CSS when building for production of course, but in case you ship the whole (big) default file, it goes from 2309.7K to 180.6K (Gzip) or even 43.6K (Brotli)!
