I edit the code but missing the correct icon (as you also mention)
Where do I edit that one? (using colors)
Just add this to /themes/colors/css/colors.css
#main-menu li#menu-contact {
background: url[../images/contact.png] no-repeat 50% 25%;
background-size: 40px;
}
I added it at line 1923
You also need a suitable image placed in /themes/colors/images. But you won’t need to add that, as I’ve used the same one you already have on your site for the colors theme 🙂
