Immagini in dark mode senza media query: usare light-dark() in CSS

Implementing dark mode often requires duplicating rules via @media (prefers-color-scheme: dark) or managing separate assets. However, the new CSS light-dark() function allows developers to choose between two values based on the active color scheme without media queries. Meanwhile, Firefox users experience dark mode through three primary methods: OS-level settings that trigger prefers-color-scheme, site-native toggles found on platforms like GitHub, or forced dark mode via extensions that intercept page content for consistency.
