The HTML

To show a video in HTML, use the element:

Example

Try it Yourself »

How it Works

The controls attribute adds video controls, like play, pause, and volume.

It is a good idea to always include width and height attributes. If height and width are not set, the page might flicker while the video loads.

The element allows you to specify alternative video files which the browser may choose from. The browser will use the first recognized format.

The text between the and tags will only be displayed in browsers that do not support the element.

HTML

To start a video automatically, use the autoplay attribute:
