To place an element on a layer below another one, it just has to have a lower value of z-index but that lower value can be negative. One area where this is useful is when using pseudo elements and wanting to position them behind the content of their parent element.

This is impossible as a child’s z-index is set to the same stacking index as its parent.
How does the Z index work?
The z-index property determines the stack level of an HTML element. The “stack level” refers to the element’s position on the Z axis (as opposed to the X axis or Y axis). A higher value means the element will be closer to the top of the stacking order. This stacking order runs perpendicular to the display, or viewport.
