HTML <input> Tag with the 'width' Attribute
<form name="myForm" action="/resources/html-forms-action.cfm">
<input type="image" src="/images/examples/australia-nz-map.gif" alt="Australia & NZ Map" name="myImageField" height="142" width="200">
</form>
The above example demonstrates usage of the <input> element with the width attribute.
The width attribute is used on input controls that use an image button (i.e. type="image").
The width is used to specify the horizontal dimension of the button. It is typically used with the height attribute which specifies the vertical dimension.
