title: Why won't .getPropertyValue() return a value for the "borderRadius" property?
body: <p>Here is the function:</p>
  
  <pre><code>function lastmenuborder() {
      var articleparent = document.getElementById('article').parentNode;
      var articlestyle = window.getComputedStyle(articleparent,null).getPropertyValue('borderRadius');
      alert (articlestyle);
  }
  </code></pre>
  
  <p>I get no value, yet the css for the parent node is:</p>
  
  <pre><code>div#mainbody div.placeholder {
      border-radius: 3px;
  }
  </code></pre>
  
  <p>What would I have to change to return "3px"? All help greatly appreciated; I am still a newb at JavaScript.</p>
