Answer

To implement a dark mode toggle with Tailwind CSS, you can utilize Tailwind's dark mode feature, which allows you to apply different styles based on the user's system preference or a class toggle. Here's a simple example using a class-based approach.

<!-- BEGIN COPY / PASTE -->
    <div class="dark:bg-gray-800 bg-white min-h-screen flex items-center justify-center">
      <button onclick="document.documentElement.classList.toggle('dark')" class="bg-blue-500 text-white px-4 py-2 rounded">
        Toggle Dark Mode
      </button>
    </div>
    <!-- END COPY / PASTE -->

Additional Comment:

Ensure your Tailwind configuration is set to use class-based dark mode by adding `darkMode: 'class'` in your `tailwind.config.js` file.
The example uses a button to toggle the "dark" class on the `documentElement`, which is the `` tag.
Dark mode styles are prefixed with `dark:` in Tailwind, allowing you to define styles for both light and dark modes.
This approach gives you full control over when dark mode is activated, independent of the user's system settings.
