HTML<source> tag

HTML <source> tag is used as a child element to define more than one media resources for <audio>, <video>, and <picture> element.

It is used to provide the same media content with different formats such as mp3, mp4, etc.

When we embed multiple resources with the same content but different format then the browser may choose the most compatible format and display or play that media file.

The <source> tag was introduced in HTML5.
