The HTML 5 <track> tag is used to specify external timed text tracks for media elements (i.e. the <video> element and the <audio> element). The text tracks specified with the <track> tag could include subtitles, captions, descriptions, chapters, and metadata.
Example Code:
<video width="300" height="240" controls>
<source src="audio/toy.mp4" type="video/mp4">
<track src="subtitles_en.vtt" kind="subtitles" srclang="en" label="English">
<track src="subtitles_it.vtt" kind="subtitles" srclang="it" label="Italian">
Your browser does not support the video tag.
</video>
