title: Select elements with class except one with specific id
body: <pre><code>$('.ui-widget-content').css('border','none');
      $('#helpDialog .ui-widget-content').addClass('HelpDialogBorder');
  </code></pre>
  
  <p>I am doing like this to remove border. But, there is an element where I want to keep border.</p>
  
  <p>Is there any way in first line itself to select all elements with class "ui-widget-content" but except one with id "helpDialog"?</p>
