I’ve found out a lot of ways of implementing a dark mode in your site. Both with Javascript and CSS. Today I’m going to share a method which doesn’t allow it to be toggled with a button but it’s the easiest way I’ve found.

For achieving this we are going to use the prefers-color-scheme media feature, which is used to detect if the user has requested to use a light or dark theme, and :root for setting global variables in CSS.

Then in any part of the site we have to use the --bg-color variable with var() like this:

You can check support for prefers-color-scheme in https://caniuse.com/mdn-css_at-rules_media_prefers-color-scheme
