我试着用：

#voltarTEST {
    width: 80px;
    height: 62px;
    padding-top: 16px;
    background-image: url(../img/multiLangImage/Seta11.png);
    background-repeat: no-repeat;
}
#seguinteBtn {
    width: 80px;
    height: 62px;
    padding-top: 16px;
    background-image: url(../img/multiLangImage/Seta21.png);
    background-repeat: no-repeat;
    text-decoration: none;
    color: #777;
}
#seguinteBtn:hover {
    background-image: url(../img/multiLangImage/Seta22.png);
    background-repeat: no-repeat;
    text-decoration: none;
    color: #FFF;
}
#voltarText {
/*  padding-right: 10px;*/
    padding-left: 30px;
}
#voltarNEText {
/*  padding-right: 10px;*/
    padding-left: 30px;
}
#voltarTEST:hover {
    background-image: url(../img/multiLangImage/Seta12.png);
    background-repeat: no-repeat;
}
#voltarTEST a {
    text-decoration: none;
    font-size: x-small;
    font-family: Verdana;
    text-decoration: none;
    color: #999;
}
#voltarTEST a:hover {
    text-decoration: none;
    font-size: x-small;
    font-family: Verdana;
    text-decoration: none;
    color: #FFF;
}
#dataUltimaSincMSG {
    margin-bottom: 0;
}
#estadoSinc {
    margin-bottom: 0;
}

但这不起作用,当我将鼠标悬停在链接上时,这只会改变颜色.
