Set the z-index for an image:
img {
position: absolute;
left: 0px;
top: 0px;
z-index: -1;
}
Definition and Usage
The z-index property specifies the stack order of an element.
An element with greater stack order is always in front of an element with a lower stack order.
Note: z-index only works on positioned elements (position:absolute, position:relative, or position:fixed).
