Definition and Usage
The width property sets or returns the value of the width attribute of a video.
The width attribute specifies the width of a video player, in pixels.
Tip: Always specify both the height and width attributes for videos. If height and width are set, the space required for the video is reserved when the page is loaded. However, without these attributes, the browser does not know the size of the video, and cannot reserve the appropriate space to it. The effect will be that the page layout will change during loading (while the video loads).
Note: Do not rescale video with the height and width attributes! Downsizing a large video with the height and width attributes forces a user to download the original video (even if it looks small on the page). The correct way to rescale a video is with a program, before using it on a page.
Browser Support
The width property is supported in all major browsers.
Note: Internet Explorer 8 and earlier versions, do not support the <video> element.
