Determining the Highest z-index in Your Document

When working with z-index, it's crucial to set a value that ensures an element appears on top of all others. However, relying on guesswork can be inefficient. This question seeks a scientific method to determine the highest z-index present in a document.

The code provided offers a solution. It iterates through all elements in the document, checking their css "position" property. If the position is not "static," it retrieves the z-index value, converting it to an integer. The resulting maximum value is stored in "maxZ."

Using this approach eliminates the need for guesswork and ensures that the desired element takes precedence over any other with a lower z-index.
