The scroll property of the VTTRegion interface is an enumerated value indicating how existing cues in the region move when a new cue is added.
Value
A string. Possible values are:
""(the empty string)-
Existing cues in the region don't scroll; instead, they are displayed at the same time as new cues. This is the default.
"up"-
New cues are added at the bottom of the region, and existing cues scroll upwards to make space for them.
Examples
In the following example, a new VTTRegion is created, then the value of scroll is set to "up". The value is then printed to the console.
js
const region = new VTTRegion();
region.scroll = "up";
console.log(region.scroll);
