title: css create rounded shadow under a square image
body: <p>Is there a way to create a rounded shadow effect underneath a square image such as the one in the image?</p>
  
  <p>I was also looking at <a href="http://nicolasgallagher.com/css-drop-shadows-without-images/demo/" rel="nofollow noreferrer">this website</a> which says that this sort of effect is possible, but their description of the code implementation is really ambiguous.</p>
