Which CSS property is used to control the spacing between elements?

The chosen answer is appropriate because the CSS property "margin" is specifically designed to control the spacing between elements. It defines the area outside an element's border, effectively creating space between different elements on a webpage. By adjusting the margin, developers can increase or decrease the space surrounding an element, which helps in achieving desired layouts and visual separation.

Other properties may influence space as well. For instance, "padding" controls the space within an element, between its content and its border, rather than affecting the space with neighboring elements. While "border" adds a visual line around an element, it does not create space in the same way as margin. The term "spacing" is not a recognized CSS property at all. Therefore, margin is clearly the most appropriate choice for managing the distance between elements.
