I tried to edit the modul tailwind, like in a tutorial. I followd the instructions but still got the same problem.
Problem: Unknown at rule @tailwind Unknown at rule @apply
@tailwind base;
@tailwind components;
@tailwind utilities;
body {
    @apply bg-gray-50;
}
@layer components {
    .btn {
        @apply bg-[#12b488] text-white px-3 py-2 rounded-md text-sm text-white;
    }
}
