In k2fields you can create overrides of templates with specificity down to an item by applying the following naming conventions. In addition as you will see below you can include item or category specific stylesheets by including them in any of the override folders.

View	Specificity\Templates	Category*	Item	Field**	CSS file
itemlist	Item		category_view_item_i[itemid].php	category_view_fields_i[itemid].fld	i[itemid].php
itemlist	Category	category_view_c[categoryid].php	category_view_item_c[categoryid].php	category_view_fields_c[categoryid].fld	c[categoryid].php
itemlist	Generic	category_view.php	category_view_item.php	category_view_fields.fld
item	Item		item_view_i[itemid].php	item_view_fields_i[itemid].fld	i[itemid].php
item	Category		item_view_c[categoryid].php	item_view_fields_c[categoryid].fld	c[categoryid].php
item	Generic		item_view.php	item_view_fields.fld

[*] In case of subtemplates as in case of category templates that call item templates we try to find the best available ones by going from the most specific ones. Ex. if we have a category specific template defined for category with ID 20 in the file category_view_c20.php the subtemplates can be either of the followings with the named order to be picked:

• category_view_c20_item_i[itemid].php
• category_view_c20_item_c[catid].php (where [catid] is 20)
• category_view_c20_item.php
• category_view_item_i[itemid].php
• category_view_item_c[catid].php (where [catid] is 20)
• category_view_item.php
