To place an element behind another element, which CSS property should you set to a negative value?

Explanation:
Stacking order determines which element appears on top when they overlap. The property that controls this is z-index. By giving an element a negative z-index, you move it behind other elements that have higher (or non-negative) z-index values, so it sits underneath in the visual stack when they overlap. Remember, z-index only takes effect on positioned elements (such as those with position: relative, absolute, fixed, or sticky); if an element isn’t positioned, z-index won’t apply. Opacity changes transparency, not layering. Position moves the element but doesn’t guarantee a behind-the-scenes layering order by itself. Display controls how an element is laid out or rendered, not its stacking position.
