<div style="background: white; height: 500px; overflow: hidden; position: relative; width: 100%;">
	<iframe src="http://www.proxy4free.com/list/webproxy_rating1.html#top_r" style="left: -60px; position: absolute; top: -310px; height: 1024px; width: 100%;" frameborder="0" marginheight="0" marginwidth="0" scrolling="no">
		You need a Frames Capable browser to view this content.
	</iframe>
</div>
<!--
	The notable code creating the effect is the embedded css, which if written out would be:
	
	div {
		height: 500px; 
		overflow: hidden; 
		position: relative; 
		width: 100%;
	}
	
	iframe {
		left: -60px;
		position: absolute;
		top: -310px;
		height: 1024px;
		width: 100%;
	}
