npx tailwindcss init

/** @type {import('tailwindcss').Config} */
module.exports = {
  content: ["./*.html"],
  theme: {
    extend: {},
  },
  plugins: [],
};

@tailwind components;
@tailwind utilities;

  },

/* src/index.css */
@tailwind base;
@tailwind components;
@tailwind utilities;

These directives tell Tailwind to inject its styles into your final CSS output.
