Video width attribute
Definition and Usage
width
attribute sets or returns the video's width attribute value.
width
The attribute specifies the width of the video player in pixels.
Tip:Always specify the height and width attributes of the video. If height and width are set, the space required by the video is reserved when the page is loaded. However, if these attributes are not present, the browser will not know the size of the video and cannot reserve appropriate space for it. The page layout will change during loading (when the video is loading).
Note:Do not use height and width attributes to resize the video! Shrinking a large video with height and width attributes will force the user to download the original video (even if it looks small on the page). The correct way to resize the video is to use it in a program and then use it on the page.

document.getElementById("myVideo").width = "500";
Example 2

var x = document.getElementById("myVideo").width;
