SCROLL-SNAP-STOP

The scroll-snap-stop property allows such a possible snap position to "trap" the scrolling operation, forcing the scroll container to stop before the scrolling operation would naturally end.

SYNTAX

CSS


            scroll-snap-stop: value;

JS


            object.style.scrollSnapStop = "value";

VALUES


            <'scroll-snap-stop'> = normal | always


            normal

The scroll container may pass over a snap position defined by this element during the execution of a scrolling operation.


            always
