Description:

The HTML 5 <video> tag is used to specify video on an HTML document. For example, you could embed a music video on your web page for your visitors to listen to and watch.

Any content between the opening and closing <video> tags is fallback content. This content is displayed only by browsers that don't support the <video> tag.

Example Code:
<video width="300" height="240" controls>
<source src="audio/toy.mp4" type="video/mp4">
Your browser does not support the video tag.
