This is one of my first script and also one of my most used. It is really easy to use! All you have to do is to include the script in the head like this:

<script src="genericMove.js" type="text/javascript"></script>

And add the class="moveme". You must also add either position: absolute or position: relative. The relitive positioned container is kind of buggy. (Not anymore!) When you move your mouse too fast the position get messed up

I made some adjustment to the code so that you could define a handle for the moving. This isn't equally easy but easy enough! You add the class="handle" and the custom attribute for="id_of_container_you_want_to_move".
