Tailwind CSS provides a built-in dark mode feature that allows you to easily switch between light and dark themes using utility classes. You can configure dark mode in your Tailwind configuration file and apply it using class-based or media-based strategies.

Example Concept: Tailwind CSS supports dark mode by allowing you to define a "dark" variant in your configuration file. You can toggle dark mode using a class (e.g., "dark") or based on the user's system preferences using the "media" strategy. Once configured, you can use dark mode utilities like "dark:bg-gray-800" to style elements differently in dark mode.

Additional Comment:

To enable dark mode, set the "darkMode" option in your tailwind.config.js to either "media" or "class".
Using "media" will automatically apply dark mode based on the user's system settings.
Using "class" requires you to manually toggle a "dark" class on a parent element, typically the or tag.
Dark mode utilities are prefixed with "dark:" and can be combined with other Tailwind classes.
