Which property would you use to change the spacing around elements?

The margin property is used to change the spacing around elements in CSS. It creates space outside of an element's border, effectively separating it from other elements within the layout.

When applying margin, you can specify different values for each side of the element (top, right, bottom, left) or use shorthand to set all sides simultaneously. This flexibility allows for precise control over the overall spacing between various components on a webpage, helping achieve the desired layout and visual hierarchy.

In contrast, the padding property changes the spacing within an element's border, affecting the distance between the element's content and its border. The spacing property does not exist in CSS, and the border property deals with the styling of the borders themselves rather than controlling the spacing around or within the element. Therefore, using the margin property is essential for adjusting the space surrounding elements effectively.
