title: Stylesheets compatible with IE 9
body: <p>I have gotten accustomed to stylesheets that have separate rules for IE and non-IE browsers. For example, I have been using CSS3 Pie to generate rounded corners and gradients in IE.</p>
  
  <p>The issue is that IE 9 supports rounded corners <strike>and gradients</strike>, and doesn't need such workarounds anymore. How can I rewrite my stylesheet to ensure that the behaviors only apply to IE 8-, and not to IE 9 ?</p>
  
  <p>Thanks!</p>
  
  <p>Edit: here is an example from the CSS3 Pie site where the rules are redundant for IE 9:
