It's possible to show webpage content in the lightbox, using iframes. In this case the "rel" attribute should be set to <code>lightframe</code>. Again it's possible to group the items, (e.g. <code>lightframe[search]</code>) but in addition to that, it's possible to control some of the iframe properties. It's possible to set the 'width', 'height' and 'scrolling' properties of the iframe. The properties are separated from the group name by a <code>|</code>, for example <code>lightframe[search|width:100px;]</code> and <code>lightframe[search|width:120px][my caption]</code>. If no grouping is being used, then the <code>|</code> is still used and the format would be <code>lightframe[|width:100px;]</code>. The properties should all be of the format "property: value;" - note the closing semi-colon.  If no iframe properties are set, then the default width and height of 400px will be used.  See below for more detailed examples.
