Answer:

The z-index is a CSS property which defines the stack order of web elements. Higher order elements will appear before any lower order element.

Note – The z-index only applies to the positioned elements. For example, position:absolute, position:relative, or position:fixed.

div {
position: absolute;
left: 10px;
top: 10px;
z-index: -1;
}
