Answer

Tailwind CSS provides a straightforward way to implement dark mode using its configuration options. You can enable dark mode by configuring the `darkMode` option in your `tailwind.config.js` file.

<!-- BEGIN COPY / PASTE -->
    // tailwind.config.js
    module.exports = {
      darkMode: 'class', // or 'media'
      theme: {
        extend: {},
      },
      plugins: [],
    }
    <!-- END COPY / PASTE -->

Additional Comment:

The `darkMode` option can be set to 'class' or 'media'.
Using 'class' requires adding a 'dark' class to your HTML element to toggle dark mode.
Using 'media' enables dark mode based on the user's system preferences.
Once configured, use `dark:` prefix with Tailwind classes to apply styles in dark mode.
