正常样式:

 position:absolute;
         left:20px;
         bottom:0px;
         650px;
         height:50px;
         z-index:1000;
         background: #CBBFAE;
         background: rgba(190,176,155, 0.4);
         border-left: 4px solid white;
         border-left: 4px solid rgba(255,255,255,0.7);
         -ms-filter:"progid:DXImageTransform.Microsoft.Alpha(Opacity=50)";
         filter: alpha(opacity=50);    
         opacity:0.5;
         color: #fff;
         line-height:50px;
    
        -webkit-transition: all 200ms;
        -moz-transition: all 200ms;
        -o-transition: all 200ms;
        -ms-transition: all 200ms;
        transition: all 200ms;

鼠标移到上面样式改变:

-ms-filter:"progid:DXImageTransform.Microsoft.Alpha(Opacity=80)";
            filter: alpha(opacity=80);    
            background: rgba(190,176,155, 0.8);
