I’m a mac addict and I’m preparing a presentation for one of my classes. I have all the content ready and I have some extra time so I am thinking of doing a menu similar to OS X’s dock magnification. I downloaded a file and found this out there, but don’t know what it means:
<script type="text/javascript" src="MacStyleDock.js"></script>
Any suggestions?

It points to a JavaScript file '.js', the file tells the js engine what to do.
