paulwpxp on "Inserting Menu Icons in Responsive Theme"

The Home one is a bit tricky, it has this in the parent's style

.front-page .menu .current_page_item a {
	background: none;
	background-color: transparent;
	background-image: none;
	filter: none;
}

On a sidenote, the menu doesn't look like it's the one created from WP dashboard under Appearance, it looks like it's the default fallback page menu ( you can see it's sorted alphabetically ), with the Home one being automatically added, this might be the reason there is no class output into the <li>

So as it is now, for the Home one, you could just use :first-child

.menu > li:first-child > a {background:red;}

or with attribute selector like this

.menu li a[href="http://yeahitsfree.com/"] {background:red;}

or this

.menu li a[title="Home"] {background:red;}
