What's the best way to implement dark mode using Tailwind CSS?

Answer

Tailwind CSS provides a straightforward way to implement dark mode using the `dark` variant. You can toggle dark mode by adding a `dark` class to a parent element, typically the `html` or `body` tag.

<!-- BEGIN COPY / PASTE -->
    <html class="dark">
      <body class="bg-white dark:bg-gray-900 text-black dark:text-white">
        <div class="p-4">
          <h1 class="text-xl font-bold">Welcome to Dark Mode</h1>
          <p>This text changes color based on the mode.</p>
        </div>
      </body>
    </html>
    <!-- END COPY / PASTE -->

Additional Comment:

To enable dark mode, apply the `dark` class to a parent element.
Use `dark:` prefix to define styles for dark mode, such as `dark:bg-gray-900`.
Toggle the `dark` class using JavaScript to switch between modes dynamically.
Ensure your Tailwind configuration includes the `darkMode` option, typically set to `'class'`.
