HTML <source> tag
For media attributes, such as <video> tag, <audio> tag, and <picture> tag, we use the <source> tag in html for adding such type of multiple media html elements in our web page.
A developer can use alternative video, audio, and picture files using the source> tag.
Syntax:
<audio controls>
<source src="# " type="# ">
<source src="# " type="#">
…….
</audio>Example
Here is an example of an audio player having two source files. The browser will select the first one that it supports:
