How do you write a fast automated script inside your frontend layout to automatically detect if a web user has enabled browser dark mode?

I want to update the visual theme styles of my general knowledge web portal automatically matching the user's system device preferences without forcing them to toggle a button manual. What media query checks this?

Utilize the native JavaScript window.matchMedia() interface matching the CSS system color scheme preference query: if (window.matchMedia('(prefers-color-scheme: dark)').matches) { // execute dark mode layout styles }. Add an active event listener to track real-time theme shifts dynamic.
