height Attribute

Where to use the height Attribute

• As Type Length:
  height is declared on the elements: object, img

Description

The height attribute may be included on an img or an object element to specify the height of the element, either in pixels or as a percentage of the available vertical space (usually the parent element's height). This attribute will override the element's natural height and the image/object will be scaled to attain this specified height. If no width attribute is specified, the image/object's natural width will be scaled by the same factor, maintaining aspect ratio.

The advantage of specifying height and width attributes is that it informs the user agent in advance how big the final rendered element will be. The correct space on the screen can be allocated for it, avoiding the need to re-flow the page content once the image/object's actual dimensions have been determined.
