title: Z Index Property
|
||
|
---
|
||
|
## Z Index Property
|
||
|
|
||
|
The z-index property specifies the stack order of an element.
|
||
|
Any positioned elements on a web page can overlap one another in a certain order, imitating a third dimension perpendicular to the screen.
|
||
|
An element with greater stack order is always in front of an element with a lower stack order. Stack order is controlled by the z-index. This property only works for elements whose position value is set to absolute, fixed, or relative.
|
||
|
|
||
|
#### Syntax
|
||
|
z-index: auto|number|initial|inherit;
|
||
|
|
||
|
#### Example
|
||
|
```
|
||
|
div {
|
||
|
position: absolute;
|
||
|
z-index: -1;
|
||
|
}
|
||
|
```
|
||
|
|
||
|
#### Values
|
||
|
Auto: Sets the stack order equal to its parents. This is default.
|
||
|
Number: Sets the stack order of the element. Negative numbers are allowed. The higher the value, the higher the element is. With an equal value of z-index the element that is described in the HTML code below will be in front.
|
||
|
Initial: Sets this property to its default value.
|
||
|
Inherit: Inherits this property from its parent element.
