I have little experience manipulating the dom other than using $( to 
get/set style elements so direct advice and a link for education would 
be appreciated.

Overall, the problem I have is a bunch of stacked divs with different 
z-indexes.  Sometimes the user will want to move a dive to the front.  
This is not a problem, but I worry that with the page open for 6 - hours 
(all functions are performed with AJAX) my z-index number will grow too 

So, what I would like to do is decrement the z-index of all the divs 
involved when incrementing the one I am bringing to the front.  I don't 
want to decrement the z-index of all the divs. 
I don't want to decrement the ones that are currently display="none" nor 
the ones that stay visible all the time, nor divs that are children of 
the stacked divs.

The stacked divs are all children of <body>, but so are some that should 
not be affected.  If it would make the job easier, I could move all the 
stacked divs into a container div.

So, how to walk though all the stacked divs to change their z-index, if 
currently being displayed ?

If prototype does not offer assistance (but I can't imagine that), let 
me know and I will post in a .js group.
