网站褪色效果在Internet Explorer中不起作用

由于某种原因，我的网站正在衰落&定位工作，并在Chrome中看起来很棒&Firefox和Internet Explorer根本没有显示出衰落的效果，对齐也完全混乱。这是编码：

    /* fade slider */
.slides {
    height:600px;
    margin:0px auto;
    overflow:hidden;
    position:relative;
    width:900px;
}
.slides ul {
    list-style:none;
    position:relative;
}
/* keyframes #anim_slides */
@-webkit-keyframes anim_slides {
    0% {
        opacity:0;
    }
    6% {
        opacity:1;
    }
    24% {
        opacity:1;
    }
    30% {
        opacity:0;
    }
    100% {
        opacity:0;
    }
}
@-moz-keyframes anim_slides {
    0% {

    }
    6% {

    }
    24% {
        opacity:1;
    }
    30% {
        opacity:0;
    }
    100% {
        opacity:0;
    }
}

    }
    30% {

    }
