Vertical scroll snap

Creates a scrollable container that will snap on elements when scrolling.

• Use display: grid and grid-auto-flow: row to create a vertical layout.
• Use scroll-snap-type: y mandatory and overscroll-behavior-y: contain to create a snap effect on vertical scroll.
• You can use scroll-snap-align with either start, stop or center to change the snap alignment.
