Chrome Prototypes Powerful CSS Functions: Expanding CSS Capabilities

Chrome is prototyping CSS Functions, a game-changer for CSS. This allows developers to create custom functions that compute values based on parameters and custom properties, acting as advanced custom properties. For instance, a `--light-dark()` function could return different colors or font weights depending on system dark mode preference, overcoming limitations of the built-in `light-dark()` function. While still in prototype form in Chrome Canary (requiring the Experimental Web Platform Features flag), this opens up massive possibilities for more expressive and flexible CSS.
