javascript - Very simple jQuery UI tooltip not working

Question

I replicated the example of this site: http://jqueryui.com/tooltip/#default

Html:

<h3 title='this is the title of hello world'>hello world</h3>

JS:

$(document).ready(function() {
  $(document).tooltip();
});

But it's still shows the regular tooltip only.

JSFiddle with added CSS resource: http://jsfiddle.net/HjPtJ/

Answer 1

As you can read here http://api.jqueryui.com/tooltip/ the tooltip widget is added in jQuery UI version 1.9, the JSFiddle has jQuery UI 1.8 added.
