Why Doesn\'t Z-Index Work for Overlaying Elements in Internet Explorer?

IE Z-Index Anomaly: Resolving the Overlapping Dilemma

In the realm of web development, the z-index property reigns supreme in determining the stacking order of page elements. However, Internet Explorer users may encounter a peculiar issue where z-index seemingly fails. This arises when attempting to overlay an element over another element that is relatively positioned.

Question:

How can an element be made to overlap a relatively positioned element in Internet Explorer? The z-index property doesn't seem to work, as it always appears behind the relatively positioned element.

Answer:

Internet Explorer exhibits an idiosyncratic behavior where relatively positioned elements often obscure absolutely positioned elements, even when the latter have a higher z-index value. To circumvent this issue, a non-obvious solution presents itself:

Declare the background URL path for the problematic element using a class with a CSS rule. This solution may seem paradoxical, but it effectively elevates the DOM precedence of the element and allows it to overlap the relatively positioned element.

Code Snippet:

<code class="CSS">.myLinkCssClass {
    background: url(#);
}</code>
