The <track> tag specifies text tracks for media elements (<audio> and <video>). You can use the <track> attribute to add subtitles to any video or audio element. Web Video Text Tracks Format (WebVTT) is a format for displaying timed text tracks (such as subtitles or captions) using the <track> element. Values that can be applied to the attribute include subtitles, descriptions, or captions.

Other attributes that can be included in the track tag:

  • kind: represents the kind of text track: caption, chapter, subtitle, description
  • label: represents the title of the text track
  • src: is a obligatory attribute and has the role of specifying the URL of the track file
  • srclang: this attribute identifies the language of the subtitles contained in that file
