I think you need to run npm run watch, because tailwind has a just in time feature to maximize performance, this feature will only compile the classes used in your project.
@mariohbrino I did run npm run watch but it still didn't work. I might have to try what @frankielee is suggesting but I don't know how to do it. Laravel nova already comes packed with tailwind but somehow this classes are not working and I don't know how to configure/find the tailwind config file.

So can you find the keyword like gray, 400?
I don't know what you tried. is there any error or warning message? Are you doing the configuration correctly?
Did you check the asset files? Did you try to publish the asset files and modify them?
