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

Internet Explorer Z-Index Enigma

In the realm of web development, Internet Explorer has presented a peculiar challenge for positioning elements. When attempting to overlap an element over another element positioned relatively, the z-index property often fails to work as expected in IE.

The Question

"How do you overlap an element over another element that is positioned relatively in Internet Explorer? Z-index doesn't work, it always appears behind the relatively positioned element."

The Puzzling Answer

Surprisingly, it seems that the solution lies in adding a background image to the class of the element that is not intended to overlap.

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

This seemingly innocuous line of code, despite its simplicity, addresses the issue by assigning a background image of no content (indicated by the URL #) to the element. By doing so, Internet Explorer treats the element as having a background, resolving the z-index conflict and allowing the overlapping element to come to the forefront.
