Pls I really need help

Pls can someone explain how z-index works.

For example, with this setting for z-index:

img {
  position: absolute;
  left: 0px;
  top: 0px;
  z-index: -1;

you will get:

But if you change the value of the z-index to 1 you get the following:

As you can see the image is now in front of the text or on top of the background layer.

This should help explain it?

Thank u very much. :grin:
