VTTCue: align property

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since January 2020.

The align property of the VTTCue interface represents the alignment of all of the lines of text in the text box.

"start"

Start alignment.

"center"

Center alignment.

"end"

End alignment.

"left"

Right alignment.

Examples

In the following example a new VTTCue is created, then the value of align is set to "start". 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.align = "start";
console.log(cue1.align);

track.addCue(cue1);
