title: Why is my jQuery UI CSS not working in JSFiddle?
body: <p>For answering questions with JavaScript input i often use Demos on <a href="http://jsfiddle.net" rel="nofollow noreferrer">JSFiddle</a>. It is very useful, but when i was answering <a href="https://stackoverflow.com/a/10474362/1219121">this tooltip</a> question i needed the usage of <a href="http://jqueryui.com" rel="nofollow noreferrer">jQuery UI</a>.</p>
  
  <p>The problem of this usage is, that you can check the jQuery UI in the Framework selection, but it loads only the js file and not the css files.</p>
  
  <p>So i decided to link to this <code>http://jqueryui.com/themes/base/jquery.ui.all.css</code> used in the official Demos of jQuery UI. => Problem solved.</p>
  
  <p>Really solved? No?!</p>
  
  <p>Because this link works great if a user has opened a jQuery Demo before, but as i did see here at my work it doesn't work if I only open the fiddle without ever having open one demo.</p>
  
  <ul>
  <li>Why is that?</li>
  <li>And how can i solve this problem?</li>
  <li>How should I link css in jsFiddles for jQuery? Also <a href="https://developers.google.com/speed/libraries/devguide?hl=de-DE#jqueryUI" rel="nofollow noreferrer">Googles CDN</a> contains only the JavaScript files.</li>
  </ul>
  
  <p><em>I don't want to host my own css file, just for posting demos on jsfiddle...</em></p>
  
  <p>PS: The JSFiddle where I mentioned this behavior is <a href="http://jsfiddle.net/neysor/r9yfw/" rel="nofollow noreferrer">http://jsfiddle.net/neysor/r9yfw/</a></p>
