I would like to change some of the CSS for the results of a Tag Menu item. I have changed tag parameters ( image size, what text appears) but want to add some margins and padding for .tagItemHeader, .tagItemView, .tagItemImageBlock. It does not appear to be in K2.css. Where can I find it.

Hello Cathy,

Try searching for "Component: Itemlist view (tag)" on your k2.css,
if you cannot find it it means you must have accidentally erased it so
download a fresh copy c/p this section to your k2.css and you can make your changes.

Regards.
