How Can I Make a Parent Element Appear Above Its Child Element Despite a Higher Z-index?

Positioning Nested Elements in the Z-Axis

In web design, it's common to have elements nested within each other. However, when it comes to positioning in the z-axis, achieving the desired effect can be tricky. This question explores a scenario where a parent element needs to appear above its child element despite having a higher z-index value.

The issue arises because setting a negative z-index for the child causes it to fall below the containing element, resulting in an undesired placement. To resolve this problem, the answer suggests removing the z-index from the parent element and assigning a negative z-index to the child. This ensures that the parent element stays on top in the z-axis without sacrificing the position of the page container.

Here's a modified example to demonstrate the solution:

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

.child {
  position: relative;
  background-color: blue;
  height: 200px;
  z-index: -10;
}

.wrapper {
  position: relative;
  background: green;
  height: 350px;
}
Copy after login
<div class="wrapper">
  <div class="parent">parent 1 parent 1
    <div class="child">child child child</div>
  </div>
  ...
</div>
Copy after login

With this updated CSS, the parent element will stay on top of the child, even though it lacks a z-index property. The child is placed below the parent due to its negative z-index, ensuring the desired overlapping effect.
