Change Top_Menu Rollover images

[Phanouman]

Hello,

I have added a button to the Top Menu - "Contact".
However, the icon beside it is the same as the "Home" button, and does not change when scrolled over.

1. How do I change the icon ?
2. How can I make the image a rollover image?

I'v already find this answer in the forum:

This is controlled by css class: #topnav ul li a.menu_home

You can create a new class entry: #topnav ul li a.menu_retailers with new icon image


But I don't know where is the file that I have to modify and what is exactly the code that I have to write for contact ?

Thank you very much for your help !
