Форумы / Cotonti / Support / Apply another skin for sub-category

with cotonti you can use logical if blocks when styling templates.
somwhere in the forums and docu should be a word about it.

the easiest way would be to just copy the old skin from the skins direcotry and save it on your hdd or somewhere else. implement the new one and do the same next year...

other than that you could use different sub styles for every skin. (some dark and white css style for example)

this style can be choosen in the users profile or can be set directly with a mysql query...
