The z-index property designates the stacking order of an element.

Syntax

z-index only works when its element has a position assigned (position: absolute, position: fixed, position: relative, or position: sticky) and on flex elements (items inside display: flex elements). Elements with a higher z-index value display in front of those with a lower value.

.classname {
  position:relative;
  z-index:1;
}

Values

auto
Default value. The stacking order of the element is set to that of its parents.

number
Positive and negative numbers are allowed. Sets the stacking order of the item.

initial
Sets the property to its default value.

inherit
Inherits this property’s value from its parent item.
