Syntax

Values

none
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.
repeat(<length-percentage>)
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.

Formal syntax

none | repeat( <length-percentage> )

where
<length-percentage> = <length> | <percentage>
