Here's a rough outline of the code/style in question.
My plugin will position an element in one of 16 predefined locations and add
a css class pertaining to that location (eg. location1). It knows nothing
about the element it's positioning. When it adds the location css class it
first has to remov

Another tip that's pertinent to Javascript and jQuery is DOM access i
