I am trying to replace the CSS on my WordPress website with TailWind. My current site’s CSS is 11Kb in size.

I installed TW and built the minimized CSS and it’s only 4kb, but it does not really contain the classes I intend to use on the HTML/PHP markup (example: bg-black). How do I make the build process recognize and generate only the classes I need?

PS: If I use the CDN TW css file, it’s 2.8MB, so that’s out of question.

I was expecting to see the basic classes.
