Deprecated: This feature is no longer recommended. Though some browsers might still support it, it may have already been removed from the relevant web standards, may be in the process of being dropped, or may only be kept for compatibility purposes. Avoid using it, and update existing code if possible; see the compatibility table at the bottom of this page to guide your decision. Be aware that this feature may cease to work at any time.
Non-standard: This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.
scroll-snap-type-y CSS property defines how strictly snap points are enforced on the vertical axis of the scroll container in case there is one.
Note: See scroll-snap-type for the standard feature.
Specifying any precise animations or physics used to enforce those snap points is not covered by this property but instead left up to the user agent.

When the visual viewport of this scroll container is scrolled vertically, it must ignore snap points.
The visual viewport of this scroll container will rest on a snap point if it isn't currently scrolled vertically. That means it snaps on that point when the scroll action finished, if possible. If content is added, moved, deleted or resized the scroll offset will be adjusted to maintain the resting on that snap point.
The visual viewport of this scroll container may come to rest on a snap point if it isn't currently scrolled vertically considering the user agent's scroll parameters. If content is added, moved, deleted or resized the scroll offset may be adjusted to maintain the resting on that snap point.
