I have been trying to use k2 with an Artisteer template and css4k2 override.
I cannot get it to work so have inserted a an override to produce a font size of 50px in div.groupleading purely as a test . It does not produce the result but I note that the override appears to be being over ridden - see the attached file.
The page in question - test site can be seen at:

I suspect the problem is the sequence of loading css in an artisteer generated template but would be grateful for any help.
