title: Why isn't my CSS working in IE?
body: <p>I set a curve style for button and tab control.  It's working properly in Firefox, but not in IE.  </p>
  
  <p>Here is the CSS:</p>
  
  <pre><code>-webkit-border-radius: 15px;
  -moz-border-radius: 15px;
  -o-border-radius: 15px;
  border-radius: 15px;
  </code></pre>
