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.

Initial value	`none`
Applies to	all elements
Inherited	no
Percentages	refer to the element’s border box
Media	interactive
Computed value	as specified, but with relative lengths converted into absolute lengths
Animation type	a position
Canonical order	the unique non-ambiguous order defined by the formal grammar

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