 			<p>Raster images are an example of an object with all three intrinsic dimensions.  SVG images designed to scale might have only an intrinsic aspect ratio; SVG images can also be created with only an intrinsic width or height.  CSS gradients, defined in this specification, are an example of an object with no intrinsic dimensions at all.  Another example of this is embedded documents, such as the <code>&lt;iframe></code> element in HTML.  An object cannot have only two intrinsic dimensions, as any two automatically define the third.</p>
