I am using a Template Monster template (I know, I know!), and they change the appearance of sideboxes according to the $box_id name. For example, in tpl_box_default_left, they have this code:

Code:
if ($box_id == 'categories')
 {
	$style_head = 'style1'; 
	$style_cont = 'style1';
 }
This then makes the categories sidebox display in a different way (i.e. it follows "style1" which is defined in another location).

I would like to continue to use this method to make other sideboxes follow specific styling guidelines, but need to know the $box_id of each sidebox. I thought I might find it by "viewing source", but it seems that many sideboxes do not have a specific div id="" (which is where I thought I would find the $box_id name).

Any suggestions? Thanks!
