title: Hide all elements except one div for print view
body: <p>I have the following CSS for my print style:</p>
  
  <pre class="lang-css prettyprint-override"><code>* {
   display:none;
  }
  
  #printableArea {
   display:block;
  }
  </code></pre>
  
  <p>I expected this to hide <em>all</em> elements, and only show the printableArea, however <em>everything</em> gets hidden. In print view, all I get is a blank page.</p>
  
  <p>I have it included properly in the HEAD, with <code>media="print"</code> on this particular stylesheet.</p>
