Z-index is used to position a CSS box along the z axis, perpendicular to the display.Wherever two boxes overlap, the box with the largest z-index will appear on top.
Syntax
z-index: index | auto | inherit ;
index - A positive or negative integer, or 0.
auto - The browser default.
inherit - inherit from the parent element.
z-index will only affect CSS boxes if they have a position value of absolute, fixed, or relative.
Examples:
body { z-index: -8; }
.emw3class { z-index: auto; }
#emw3id { z-index: 1; }
Try it:
The Z-index of the pink box is the default (0), if the z-index of this text is made larger than 0 then it will appear on top. |
