+	<script>responsiveEnhance(document.getElementById('media-object'), 320);</script>
 
 This tells the browser which image to replace, and at what viewport width to replace it. When JavaScript is disabled (or unavailable), users will get the smallest image. Otherwise, when the viewport is larger than 320px, the larger image will be displayed after the smallest one has finished downloading.
 
 Finally, we need to override the default styling of images. For the detection to work, we need the smaller image to scale larger than its native size. We can do this as follows:
 
 	img.media-object {
-    	margin: 0 auto;
-    	width: 100%;
-    	max-width: 50em; /* 800px */

 Still, as we examine the fluidity of our pattern portfolio, we can quickly see that although it scales, there are points where we would ideally make the layout a little smarter, adapting it as the width of the browser increases.
