Dark Mode

Windi CSS has out-of-box Dark Mode support.

By prefixing the dark: variant to utilities, they will only apply when dark mode is enabled. With the following example, the Preview text will be red on the light mode, and green on the dark mode. Try to play with it:

CSS

We have two modes for enabling dark mode, class mode and media query mode. By default, class mode is enabled.

Class mode

Class mode gives you better control over when dark mode should enable.

windi.config.js
export default {
  darkMode: 'class',
  // ...
}

It detects the parent element's class="dark", and usually you can apply it on the html element to make it work globally.

<html>
<body>
  <!-- Dark mode disabled -->
</body>
</html>

<html class="dark">
<body>
  <!-- Dark mode enabled -->
</body>
</html>

You can use the following snippet to make the color scheme match with the user's system preference, or write your own logic to manage it.

if (window.matchMedia('(prefers-color-scheme: dark)').matches)
  document.documentElement.classList.add('dark')
else
  document.documentElement.classList.add('light')

Media query mode

In media query mode, it uses the built-in @media (prefers-color-scheme: dark) query from the browser that always matches with the user's system preference.

windi.config.js
export default {
  darkMode: 'media',
  // ...
}
