上正常使用

ul li a{color: black;background:url(http://mwv3.webs.com/menu_hover.png)-20px bottom no-repeat;
    padding:0px 0px 9px 0px;width:100%;
        -webkit-transition: background .5s ease;
         -moz-transition: background .5s ease;
           -o-transition: background .5s ease;
          -ms-transition: background .5s ease;
              transition: background .5s ease;
    display:block;/*ADDED*/
}

ul li a:hover{

background:url(http://mwv3.webs.com/menu_hover.png) center bottom no-repeat; /*Changed*/
}
