Categories Dressing

[giuly]

hello glenn
thanks for your reply via pm, ok I write here.
My site is
www_giocattoliamo_it
so
if you see I have divided the 3 groups of categories
categorie giocattoli
giocattoli in legno
giocattoli neonati

(in future I have to add a new group)

Now I would to know
how to disable bullet gif, because before are without gif on the various categories, and I wouldn't the effect when you click on a category (blue bar when I pass with mouse on 1 category)

and please I attach the previous css file, I would the same configuration (not the configuration of standard category dressing stylesheet).

previous css in zip file

Please and
thank you in advance
then I have another some questions (but are little bit)
