Answer

To implement a dark mode toggle in Tailwind CSS, you can use the "dark" variant to apply different styles based on a dark mode class on the root element. Here's a simple example of how you can set up a dark mode toggle using Tailwind's built-in utilities.

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

Additional Comment:

The "dark" variant in Tailwind allows you to define styles that apply when a parent element has the "dark" class.
In this example, the "dark" class is toggled on the root div element to switch between light and dark modes.
Ensure your Tailwind configuration includes the "darkMode" option set to "class" to enable this functionality.
This approach uses JavaScript to toggle the class, but you can also manage it through frameworks or libraries for state management.
