Stacking Context
CSS Stacking Context
A three-dimensional conceptualization of HTML elements along the z-axis, created by specific CSS properties.
तकनीकी विवरण
CSS stacking context 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).
उदाहरण
```css
/* Example: Stacking Context */
.element {
/* Apply stacking context to this element */
display: block;
margin: 0 auto;
}
```
