Syntax

width=" { number | percentage } "

Description

An object doesn’t require a width attribute but, like the height attribute, it has its uses (refer to the advantages set out in the height attribute reference).

If the width attribute is set by itself, but no height attribute is set, the object will be rescaled proportionally (assuming that object is a simple image).

In every other respect, the width attribute is identical in usage and behavior to the height attribute.

Example

Here, the width attribute is set to "200":

<object data="giant-dog.jpg" height="100" width="200">
</object>

Value

This attribute takes as its value a number representing the width of the object in pixels.

This attribute’s compatibility is dependent on the type of object to which it’s applied. For objects of type image, excellent cross-browser support is provided for the height attribute.
