width

W3C Recommendation

Summary

Specifies the width, in pixels, of certain content elements.


Applies to HTMLImgElement

The width attribute specifies the visual width of img, iframe, embed, object, video, canvas, and input[type="image"] in pixels.

By default, elements will not preserve aspect ratio when width attribute is set, without a height attribute. If a width attribute is set, but no height, an image will scale to preserve its original aspect ratio. If both the width and height are zero, the element should not be intended to be visible by the user.

Width values must be non-negative integers.

Examples

<img> with width attribute.

<canvas> with width attribute

HTML

<canvas width="200" height="200"></canvas>
