Definition and Usage

overscroll-behavior-y The property is used to disable the scroll chain or over-scroll feedback when trying to scroll beyond the scroll boundaries in the y-direction.

Scroll Chainrefers to the behavior where over-scrolling on an element causes the parent element to scroll. This is the default behavior.

Over-scrollFeedback is provided when the user tries to scroll beyond the scroll boundaries. For example, on mobile devices, when trying to scroll beyond the top of the page, it is usually accompanied by a visual feedback of page refresh.

Example

Disable the scroll chain of the scrollable <div> element:

#yellowDiv {
  overscroll-behavior-y: contain;
}
