title: How to override jQuery-ui.css styles
body: <p>I've implemented the jQuery-ui tabs widget and it works great.  However, it does some style things I don't like. Specifically the .ui-corner-all is rounded, and I don't want that. </p>
  
  <p>What is the "correct" way to override this. Should I use a theme?</p>
  
  <p>Does someone have a good beginner tutorial on how to use/create ui themes?  </p>
