CSS z-index
- The z-index property in CSS is used to control the stacking order of elements on a web page.
It determines which element appears in front of or behind another element when they overlap.
Elements with a higher z-index value appear above elements with a lower z-index value.
Syntax
selector {
z-index: value;
}
Important points
- The z-index property works only with positioned elements.
- It can be used with relative, absolute, fixed, and sticky positions.
- Positive values move elements forward.
- Negative values move elements behind other elements.
