Answer

To create a dark mode toggle using Tailwind CSS, you can utilize Tailwind's dark mode feature, which allows you to apply different styles based on a dark or light theme. This typically involves toggling a class on the HTML element.

<!-- BEGIN COPY / PASTE -->
    <html lang="en">
    <head>
      <script>
        function toggleDarkMode() {
          document.documentElement.classList.toggle('dark');
        }
      </script>
    </head>
    <body class="bg-white dark:bg-gray-900 text-black dark:text-white">
      <button onclick="toggleDarkMode()" class="p-2 bg-gray-200 dark:bg-gray-800 rounded">
        Toggle Dark Mode
      </button>
      <div class="p-4">
        <p class="text-lg">This is a paragraph with responsive text color.</p>
      </div>
    </body>
    </html>
    <!-- END COPY / PASTE -->

Additional Comment:

Tailwind's dark mode is configured in the `tailwind.config.js` file, typically using the `media` or `class` strategy.
The example uses the `class` strategy, which toggles the `dark` class on the HTML element.
Ensure your Tailwind configuration is set to use dark mode by adding `darkMode: 'class'` in the config file.
Use `dark:` prefix in class names to apply styles in dark mode.
This approach requires JavaScript to toggle the class, as shown in the example.
