Answer

To implement a dark mode toggle with Tailwind CSS, you can use the "dark" variant provided by Tailwind. This involves adding a class to the HTML element that triggers dark mode styling based on user interaction.

<!-- BEGIN COPY / PASTE -->
    <html lang="en" class="dark">
    <body class="bg-white dark:bg-gray-900 text-black dark:text-white">
      <button onclick="document.documentElement.classList.toggle('dark')">
        Toggle Dark Mode
      </button>
      <p class="p-4">This text changes color based on the mode.</p>
    </body>
    </html>
    <!-- END COPY / PASTE -->

Additional Comment:

Tailwind's dark mode is configured in the `tailwind.config.js` file, typically using the `class` strategy.
Ensure your Tailwind CSS is configured to support dark mode by setting `darkMode: 'class'` in the configuration file.
The `dark` class on the HTML element triggers the dark mode styles.
Use JavaScript to toggle the `dark` class on the root element to switch between modes.
