The href value here is wrong for a few reasons and will not work.  
First is that
href values which refer to a file system directory for a browser to  
lookup must
start with 'file:///'. Second is whether one can even make a browser  
pick up a
local filesystem file by mentioning it in a href like this. Third is  
that your back
slashes are properly escaped properly and it isn't going to be what  
you want.
Try using Python to print the value of your string and you will see  
what I mean.

Is you css.css file in the same directory as your publisher .py  
files? What Apache
configuration have you used to enable the use of mod_python, did you use
SetHandler or AddHandler? If you used SetHandler, then all requests  
go to
mod_python and a static .css file will never be able to be served up.

There could also be issues dependent on which URL you used to access the
resource in the first place as publisher is really sloppy about how  
it deals with
trailing slashes and it is possible to have URLs notionally targeting  
different
levels in the URL hierarchy ending up at the same resource with the  
result
being that relative URLs are broken.

In summary, post the snippet of Apache configuration that you are  
using to
enable use of mod_python.publisher. Also indicate what URL you are using
and where the .css file is located relative to the .py files.
