Answer
To implement a dark mode toggle in a Tailwind CSS project, you can use Tailwind's built-in dark mode feature, which allows you to apply different styles based on a class or media query. Here's a simple example using class-based dark mode.
<!-- BEGIN COPY / PASTE -->
<div class="min-h-screen bg-white dark:bg-gray-900 text-black dark:text-white">
<button onclick="document.documentElement.classList.toggle('dark')" class="p-2 bg-gray-200 dark:bg-gray-800 rounded">
Toggle Dark Mode
</button>
<p class="mt-4">This is a paragraph that changes color based on the mode.</p>
</div>
<!-- END COPY / PASTE -->Additional Comment:
- Ensure your Tailwind configuration (`tailwind.config.js`) has `darkMode: 'class'` set to enable class-based dark mode.
- The `dark` class is toggled on the `html` element to switch between light and dark modes.
- Use `dark:` prefix in your Tailwind classes to define styles for dark mode.
- This example uses JavaScript for toggling; you can also use frameworks like React or Vue for more complex state management.
