How does Tailwind CSS handle dark mode implementation?

Tailwind CSS handles dark mode using a ‘dark’ variant. The utility classes can easily style elements in dark mode by adding a prefix to them: ‘dark:bg-gray-800’. Out of the box, Tailwind uses the ‘media’ strategy to apply dark mode styles automatically using the user’s preference. Other options would be to depend on the ‘class’ strategy, which by default enables and disables dark mode by adding a class of ‘dark’ to the root. This allows custom dark mode switches within an application. This more straightforward approach makes dark mode an integrated part of Tailwind’s utility-first workflow, and styling and customization of dark mode will become much easier.
