Jquery-ui library will not loaded/served by Google CDN from the Google site “insert html box”
I am struggling with the Google sites "insert html box" tool to get the CDN to serve the jQuery user interface library — jQueryUI — without any success.
I have used the following code and its variants without any themes but to no avail;
<link rel="stylesheet" href="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8.21/themes/base/jquery-ui.css"/>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/jqueryui/1.8.18/jquery-ui.min.js" type="text/javascript"></script>
The jQuery library loads fine but not the jQueryUI library. The Google developer site suggests that this should work, but I only get error messages — "failed to load external url jquery-ui.css" or "folding element body into parent".
What am I doing wrong?
