What is width Attribute in HTML <video> Tag?

We use the width attribute when we want to set the width of the target video player.

It’s a good practice to always set the size of a video player (including its height) so that browsers know how much space that video player takes in a document.

The value we set for this attribute could be any number of HTML supported units.
