background-image: url();
background-repeat: no-repeat;
}

a[href="/search?search_id=unanswered"]:hover {
color: white;
}

a[href="/search?search_id=egosearch"]{
background-image: url();
background-repeat: no-repeat;
}

a[href="/search?search_id=egosearch"]:hover {
color: white;
}

a[href="/search?search_id=newposts"]{
