How to Place a Parent Element Above its Child Using CSS Z-index?

Achieving Parent Element Above Child

When encountering nested CSS elements, there may be a need to display the parent element above the child element in the z-axis. While setting z-index on both elements alone may not be sufficient, there is an effective solution:

Negative Z-Index for the Child

Remove the z-index property from the parent element and assign a negative z-index value to the child element. This will position the child element behind the parent element, essentially bringing the parent to the foreground.

Consider the following code:

.parent {
  position: relative;
}
.child {
  position: absolute;
  background-color: blue;
  z-index: -1;
}

In this scenario, the parent element has a position that places it on the normal flow of the page, while the child element's position is relative to the parent. The negative z-index assigned to the child element ensures that it appears behind the parent element.

By applying this technique, you can effectively achieve the desired arrangement of having the parent element on top of the child element in the z-axis, without affecting the positioning of other elements in the page.
