The HTMLVideoElement interface provides special properties and methods for manipulating video objects. It also inherits properties and methods of HTMLMediaElement and HTMLElement.

The list of supported media formats varies from one browser to the other. You should either provide your video in a single format that all the relevant browsers supports, or provide multiple video sources in enough different formats that all the browsers you need to support are covered.

Properties

Inherits properties from its ancestor interfaces, HTMLMediaElement, and HTMLElement.

HTMLVideoElement.height
Is a DOMString that reflects the height HTML attribute, which specifies the height of the display area, in CSS pixels.
HTMLVideoElement.poster
Is a DOMString that reflects the poster HTML attribute, which specifies an image to show while no video data is available.
HTMLVideoElement.videoHeight Read only
Returns an unsigned long containing the intrinsic height of the resource in CSS pixels, taking into account the dimensions, aspect ratio, clean aperture, resolution, and so forth, as defined for the format used by the resource. If the element's ready state is HAVE_NOTHING, the value is 0.
HTMLVideoElement.videoWidth Read only
Returns an unsigned long containing the intrinsic width of the resource in CSS pixels, taking into account the dimensions, aspect ratio, clean aperture, resolution, and so forth, as defined for the format used by the resource. If the element's ready state is HAVE_NOTHING, the value is 0.
HTMLVideoElement.width
Is a DOMString that reflects the width HTML attribute, which specifies the width of the display area, in CSS pixels.
