The **`<track>`** [HTML](https://developer.mozilla.org/en-US/docs/Web/HTML) element is used as a child of the media elements, [`audio`](audio!) and [`video`](video!). It lets you specify timed text tracks (or time-based data), for example to automatically handle subtitles. The tracks are formatted in [WebVTT format](https://developer.mozilla.org/en-US/docs/Web/API/WebVTT_API) (`.vtt` files) — Web Video Text Tracks.
