Answer

Tailwind CSS provides a "dark" variant that allows you to easily implement dark mode by toggling a class on the root element. You can use the "dark" class to apply different styles when dark mode is active.

<!-- BEGIN COPY / PASTE -->
    <html lang="en">
    <body class="dark:bg-gray-900 bg-white text-gray-900 dark:text-white">
      <div class="p-4">
        <h1 class="text-2xl font-bold">Dark Mode Example</h1>
        <p class="mt-2">Toggle dark mode to see the effect.</p>
      </div>
      <button onclick="document.body.classList.toggle('dark')" class="mt-4 p-2 bg-blue-500 text-white rounded">
        Toggle Dark Mode
      </button>
    </body>
    </html>
    <!-- END COPY / PASTE -->

Additional Comment:

Tailwind's "dark" variant allows you to define styles for dark mode using the "dark:" prefix.
To toggle dark mode, you can add or remove the "dark" class on the root element, typically the tag.
This example uses a simple JavaScript function to toggle the "dark" class.
Ensure your Tailwind configuration is set to use the "media" or "class" strategy for dark mode.
