CSS scroll snap points are often used as a mechanism to create scroll interactive "selection" components, giving authors control over what areas of its content a scrolling container can settle.This proposal adds 2 JavaScript events, snapchanging, and snapchanged, which fire in response to the scrolling/snapping of containers which snap.
snapchanging (explainer) is a JavaScript event that aims to let the web page know, as early as possible, that a scrolling operation will result in a change in the element the container being scrolled is snapped to.
snapchanged (explainer) is a JavaScript event that fires when a scrolling operation is complete and the scroller has snapped to a different element than it was previously snapped to.
