Boh, io avevo provato cis' un po' di tempo fa ed andava. Se riesco a ritrovarti l'esempio lo posto. Prova ad utilizzare la riecerca nel forum per vedere se ci sono altre indicazioni
Dall'help di Joomla:
Menu Class Suffix: This field can contain a suffix that will be applied to the CSS classes for the Menu styles of this page. This allows individual Menu styling with relative ease. For example, if the suffix .foo is entered here, all CSS code elements in the CSS file within the Template for Menu styles will have .foo added to them. table.moduletable becomes table.moduletable.foo. Separate entries would then need to be added in the CSS file of the Template, for each corresponding difference.
Module Class Suffix: This field can contain a suffix that will be applied to the CSS classes for the Module styles of this page. This allows individual Modules styling with relative ease. For example, if the suffix .foo is entered here, all CSS code elements in the CSS file within the Template for Modules will have .foo added to them. Separate entries would then need to be added in the CSS file of the Template, for each corresponding difference.
Ciao,
