Use the width attribute in HTML to set the width of an element. You can use the attribute with the following elements − <canvas>, <embed>, <img>, <input>, <video>, etc.
Example
You can try to run the following code to implement width attribute in HTML −
<!DOCTYPE HTML> <html> <body> <video width="300" height="200" controls autoplay> <source src = "/html5/foo.ogg" type = "video/ogg" /> <source src = "/html5/foo.mp4" type = "video/mp4" /> Your browser does not support the video element. </video> </body> </html>
