The HTML5 track Tag
It is quite unfortunate that the HTML5 <track> tag is not recognized in major web browsers like the Internet Explorer, Google Chrome, Safari, Opera and Firefox. However, the HTML5 <track> tag is capable of defining the succeeding track for the <audio> and <video> elements. The good news is that HTML5 <track> tag is well-matched with the Event Attributes and Global Attributes in HTML5.
The HTML <track> tag is newly incorporated in HTML5 and it has never been used in HTML4.01.
The optional attributes that can be used for HTML5 <track> tag are the following:
