<label for="lname">Last name:</label>

Definition and Usage
The width attribute specifies
the width of the <input> element.
Note: The width attribute is used only with
<input type="image">.
Tip: Always specify both the height and
width
attributes for images. If height and width are set, the space required for the
image is reserved when the page is loaded. However, without these attributes,
the browser does not know the size of the image, and cannot reserve the
appropriate space to it. The effect will be that the page layout will change
during loading (while the images load).
Browser Support
The numbers in the table specify the first browser version that fully supports the attribute.
