How does the CSS z-index property work?(2 Points)Determines the order of stacking for positioned elementsSets the font size of an elementControls the transparency of an elementSpecifies the indentation of an element

The CSS z-index property works by determining the stacking order of positioned elements in a webpage. This means it controls which elements appear in front and which ones appear behind when elements overlap on the page.

Here are the steps on how it works:

1. The z-index property only works on elements that have a position value other than static (like relative, absolute, or fixed).
2. Elements with a higher z-index will appear in front of elements with a lower z-index.
3. If elements have the same z-index, the one that comes last in the HTML will appear on top.
4. The default z-index value is auto, which equates to 0 where no z-index is specified.

Please note that z-index does not set the font size, control the transparency, or specify the indentation of an element. Those are controlled by other CSS properties.
