Tailwind classes stopped working (only previously used and customly added classes work)

For some reason my tailwind doesn't work anymore. I was able to use any classes and they were being added to style.css with: "npx tailwindcss -i tailwind.css -o ./css/style.css --watch". But today it just stopped working, I can't apply even the most default class like text-red-400. I can only use classes that I have previously already used AND ones that I have customly added.

What do you hate the most as UI developer?
I personally hate grids the most.

Quite passionate

Do you recommend Brave over Chrome? Does Brave use less RAM and CPU?

Don't you all love github conflicts?

When they say they are looking for Intern with experience???
