title: HTML5 framework
body: <p>I know very little HTML or web dev, but I would like to write an
  HTML5 app with a fairly complex UI. Is there a framework that stands
  out among the rest for this type of job? Do I need a framework; or can
  I just do everything in straight HTML+CSS+JS? And what about GWT?</p>
  
  <p>Thanks!</p>
