'Tailwind installation doesn't apply the CSS in any of my projects

I installed Tailwind CSS in a mock project because I've had problems with Tailwind before. I follow the installation guide on their website but the CSS doesn't seem to be working. Here is the link to the repo. I used this to setup the mock project for testing. Does anyone know what the problem is?

@tailwind base;
@tailwind components;
@tailwind utilities;

I have the annotations above in my CSS files.
