Tailwind CSS provides a straightforward way to handle dark mode toggling using its dark mode feature. You can configure Tailwind to apply dark mode styles conditionally based on a class or media query.

Example Concept: Tailwind CSS supports dark mode by allowing you to define styles that apply when a specific class (usually "dark") is present on the root element. You can configure this in your `tailwind.config.js` file by setting `darkMode` to "class". This enables you to toggle dark mode by adding or removing the "dark" class on the `` or `` element, allowing you to define dark mode styles using the `dark:` prefix on your utility classes.

Additional Comment:

To enable dark mode, update your `tailwind.config.js` with `darkMode: 'class'`.
Use the `dark:` prefix to specify styles that should apply in dark mode, e.g., `dark:bg-gray-800`.
Toggle the "dark" class on the root element using JavaScript to switch between light and dark modes.
Consider user preferences and provide a toggle button for a better user experience.
