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.

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.

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;




The scroll container does not define any snap points. Elements within the scroll container may still define snap points on behalf of the scroll container.


Defines an interval at which snap points are defined, starting from the container's relevant start edge. Only positive lengths are allowed. Percentages refer to the width of the container.
