How can I optimize Tailwind CSS build output for better performance in production?

Answer

To optimize Tailwind CSS build output for production, you should use the `purge` option to remove unused styles, which significantly reduces the file size. This is typically done by configuring Tailwind to purge unused styles based on your project's HTML, JavaScript, and other template files.

<!-- BEGIN COPY / PASTE -->
    // tailwind.config.js
    module.exports = {
      purge: ['./src/**/*.{js,jsx,ts,tsx,html}'],
      darkMode: false, // or 'media' or 'class'
      theme: {
        extend: {},
      },
      variants: {
        extend: {},
      },
      plugins: [],
    }
    <!-- END COPY / PASTE -->

Additional Comment:

Ensure your `purge` paths accurately reflect where your HTML and component files are located.
Consider using a tool like `postcss` with `autoprefixer` to further optimize your CSS for cross-browser compatibility.
Always test your production build to ensure no necessary styles are accidentally purged.
