scroll-margin

The scroll-margin CSS shorthand property sets all of the scroll margins of an element at once, assigning values much like the margin property does for margins of an element.

Thus, the scroll-margin values represent outsets defining the scroll snap area that is used for snapping this box to the snapport. The scroll snap area is determined by taking the transformed border box, finding its rectangular bounding box (axis-aligned in the scroll container’s coordinate space), then adding the specified outsets.

Values: <length> An outset from the corresponding edge of the scroll container.

Syntax example: scroll-margin: 10px;
