When Z-Index Fails: How to Position One Div Above Another

Using z-index to Position One Div Above Another

To ensure that a specific div remains above another, leveraging the z-index property may not always suffice. To rectify this, consider implementing the following enhancements:

1. Establish Position Context:
Assign position: relative to both divs to create a stacking context. This ensures that each div's positioning is assessed within its own context, allowing the z-index to take effect.

2. Set z-index Values:
Assign different z-index values to the divs to establish their vertical stacking order. Higher z-index values denote elements positioned closer to the foreground.

3. Adjust Other Positioning Properties:
Modify other positioning attributes as needed, such as top, bottom, margin-top, etc., to further refine the relative positioning of the divs.

Here's an updated code snippet showcasing the aforementioned techniques:

<code class="css">div {
  width: 100px;
  height: 100px;
}

.div1 {
  background: red;
  z-index: 2;
  position: relative;
}

.div2 {
  background: blue;
  margin-top: -15vh;
  z-index: 1;
  position: relative;
}</code>

<code class="html"><div class="div1"></div>
<div class="div2"></div></code>

By implementing these enhancements, you can effectively position one div above another, ensuring that it remains in the desired visual hierarchy.
