Good evening, I say that I'm not an expert on Joomla, I would like to change the font of the menu that is at the position "footermenu", in that of the top (position "hornav" I used the following code:

.hornav {font-family:Chantelli_Antiqua;}

but unfortunately if I want to change to the "footermenu" position it does not work.

.footermenu {font-family:Chantelli_Antiqua;}

Surely I'm wrong, but what?

Thank you
