Relative Color Syntax
CSS Relative Color Syntax
A syntax for deriving new colors from existing ones by modifying individual channels (e.g. lighten, desaturate).
Détail technique
CSS relative color syntax is part of the CSS specification maintained by the W3C CSS Working Group. Browser rendering engines (Blink, WebKit, Gecko) implement the specification through their layout and paint pipeline stages. Understanding the rendering pipeline — Style → Layout → Paint → Composite — is key to writing performant CSS. Properties that trigger layout recalculation (width, height, margin) are more expensive than those that only trigger compositing (transform, opacity).
Exemple
```css
/* Example: Relative Color Syntax */
.element {
/* Apply relative color syntax to this element */
display: block;
margin: 0 auto;
}
```
