DeprecatedThis 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.

The scroll-snap-points-y CSS property defines the vertical positioning of snap points within the content of the scroll container they are applied to.

/* Keyword value */
scroll-snap-points-y: none;

/* Repeated snap points */
scroll-snap-points-y: repeat(400px);

/* Global values */
scroll-snap-points-y: inherit;
scroll-snap-points-y: initial;
scroll-snap-points-y: unset;
