title: toggling css classes using knockout
body: <p>I am trying to do some like this. is it a valid syntax? I am checking for some flag value and toggling b/w two css classes?</p>
  
  <pre><code>&lt;div data-bind="visible:'anchorJobContractor'===JobDetail_SelctedTab(), css:IsTabsCollapsed ? TabCollapsed : TabExpanded"&gt;&lt;/div&gt;
  </code></pre>
  
  <p>First part visible dataBinding  works for me.</p>
