How to Make a Parent Element Appear Above Its Child in CSS?

How to Elevate Parent Element Above Child in the Z-Axis

In CSS, achieving the desired stacking order of nested elements can be challenging. This question tackles the scenario where a child element appears above its parent element in the z-axis, and setting only the z-index is insufficient.

To address this, the solution involves setting a negative z-index value for the child element. By contrast, any z-index setting on the parent element should be removed. This will effectively raise the parent element above the child in the z-axis while maintaining the desired positioning of the elements within the document structure.

Consider the following code example:

.parent {
  position: relative;
  width: 350px;
  height: 150px;
  background: red;
  border: solid 1px #000;
}

.child {
  position: relative;
  background-color: blue;
  height: 200px;
  z-index: -1;  // Negative z-index applied to the child element
}

.wrapper {
  position: relative;
  background: green;
  height: 350px;
}

With this modification, the parent element will now appear on top of the child element in the z-axis, effectively resolving the issue described in the original question.
