Found this and figured it out
http://vanweerd.com/how-to-replace-t...igation-menus/
I had to add text-indent to separate CSS class. I had it added like this
#nav li.facebook a {
background: url(images/mpfacebook.jpg) no-repeat center left;
padding: 7px 20px 5px 15px;
text-indent: -9999px;
}
had to remove it from there and add it here without the "a"
#nav li.facebook {
text-indent: -9999px;
}
