Definition and Usage
width attribute specifies the width of the video player.
Tip: predetermined width and height of the video is a good habit. If you set these properties, when the page loads will set aside space for the video. If you do not set these properties, the browser can not be pre-determined dimensions of the video, so you can not reserve a suitable space for the video. As a result, in the process of loading the page, its layout will change.
Note: Do not scale the video by height and width attributes!By height and width attributes to narrow the video will only force the user to download the original video (even though it looks small on the page). Before the correct approach is to use the video on the page, using the software for video compression.
