Html source tag

The HTML <source> tag is used to specify multiple media resources on media elements (such as <audio> and <video>).

This element allows you to specify alternative video and audio files which the browser may choose from based on its media type or codec support.

The <source> tag was introduced in HTML 5.

Example

In the example below, two files have been specified. The browser should choose which file (if any) it has support for.

<audio controls>
<source src="/music/good_enough.wma" type="audio/x-ms-wma">
<source src="/music/good_enough.mp3" type="audio/mpeg">
<p>If you are reading this, it is because your browser does not support the HTML 'audio' element.</p>
</audio>
