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>
