scroll-snap-coordinate

This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for usage in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the specification changes.

Summary

The scroll-snap-coordinate CSS property defines the positions in x and y coordinates within the element which will align with the nearest ancestor scroll container's scroll-snap-destination for the respective axis.

If the element has been transformed, the snap coordinate is transformed in the same way in order to align the snap point with the element as it is displayed.

Syntax

/* Keyword value */
scroll-snap-coordinate: none;

/* <position> values */
scroll-snap-coordinate: 50px 50px;                   /* Single coordinate */
scroll-snap-coordinate: 100px 100px, 100px bottom;   /* Multiple coordinates */

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

Values

none
Specifies that the element does not contribute to a snap point.
<position>
Specifies the offset of the snap coordinates from the start edge of the element’s border box. For each pairing, the first value gives the x coordinate of the snap coordinate, the second value its y coordinate.

Formal syntax

none | <position>#

where
<position> = [[ left | center | right | top | bottom | <percentage> | <length> ] | [ left | center | right | <percentage> | <length> ] [ top | center | bottom | <percentage> | <length> ] | [ center | [ left | right ] [ <percentage> | <length> ]? ] && [ center | [ top | bottom ] [ <percentage> | <length> ]? ]]
