Nice CSS3 Based Loading Spinner

A nice looking loading spinner that creates an animated loader for Ajax requests in a creative way, based on CSS3 animations.

How to use it:

Load the prefixfree.min.js in the document.

<script src='prefixfree.min.js'></script>

Create the Html for the loading spinner.

<ul>
<li id='a'></li>
<li id='b'></li>
<li id='c'></li>
<li id='d'></li>
<li id='e'></li>
<li id='f'></li>
<li id='g'></li>
<li id='h'></li>
<li id='i'></li>
</ul>
