The z-index is a CSS property that sets elements’ stacking order in the skin. An element’s z-index can be changed in its Advanced Properties. This is commonly used to ensure that hotspot images and their text fields or pop-up images are displayed in the correct stacking order, especially when close or overlapping.
Pinned elements are at the lowest of the stack as they are pinned to the panorama.
