Z-index: Set the Z axis parameter (three-degree space) Configurable value: auto (when the element position is repeated, the elements written in the original code on the back will appear above the elements written in the front) Parameters: <Number> decimal place. The element with a large value appears above the element with a small value. Example: div {z-index: 3} or <Div style = "Z-index: 3">
