VTTCue: lineAlign property

Limited availability

This feature is not Baseline because it does not work in some of the most widely-used browsers.

The lineAlign property of the VTTCue interface represents the alignment of this VTT cue.

Value

A string containing one of the following values:

"start"

Start alignment.

"center"

Center alignment.

"end"

End alignment.

Examples

In the following example a new VTTCue is created, then the value of lineAlign is set to "center". The value is then printed to the console.

js
let video = document.querySelector("video");
let track = video.addTextTrack("captions", "Captions", "en");
track.mode = "showing";

let cue1 = new VTTCue(0, 0.9, "Hildy!");
cue1.lineAlign = "center";
console.log(cue1.lineAlign);

track.addCue(cue1);
