where to find $box_id?

I am having trouble finding what $box_id is for various different sideboxes. I see it is set in the column_left.php and column_right.php files:

$box_id = zen_get_box_id($column_left_display->fields['layout_box_name']); )

but I don't see where to find a value I can use in CSS. For example, the sidebox heading is created in includes\templates\CUSTOM\common\tpl_box_default_left.php:

The $box_id is used in the id field. If I want to style only the category box heading, I need the category $box_id. I noticed the cPath number for products and categories could be found in the administration panel somewhere. Is this the case with $box_id?

Thanks,
Tobyn

$box_id has nothing to do with CSS.

Install the Firefox browser, then the Web Developer plugin.

Hit CTRL - SHIFT - Y , and hover over sections of the page to see the applicable css ids and classes for the various sideboxes.
