How to Fix: z-index not working with position absolute

The z-index property is not being applied correctly due to the position absolute style. To fix this, add !important to the z-index value.

Quick Answer: Add !important to the z-index value of #popupContent, e.g., $("#popupContent").css('z-index', '1001!important');

The z-index property is used to determine the stacking order of elements. In this case, the #popupContent element has a higher z-index value (1000) than the #popupFrame element (1), which means it will be displayed on top of the #popupFrame element.
