Dark mode
As we mentioned before in the Theme section NextUI comes with two default
themes lightand dark. So using the dark theme is as simple as adding it to the className of the
html / body or main element.
This will enable the dark mode for the whole application. However, many applications require the capability to switch between different themes. For this purpose, we recommend using a theme switch library or creating your own implementation.
Using next-themes
For applications using Next.js, the next-themes library is an excellent choice. It comes packed with features that enhance the user experience when transitioning between themes.
For more information, refer to the next-themes documentation.

Note: We're using the
