淘宝导航css代码 一级菜单半透明

淘宝导航加了个CSS后，一级菜单和二级菜单背景想要半透明。有没有大侠可以帮忙修改一下呢？代码如下：
.skin-box-bd{background:#399ec7;}.skin-box-bd .menu-list{background:#399ec7;}.skin-box-bd .menu-list .menu{background:#399ec7;border:none;}.skin-box-bd .menu-list .menu .link{background:#399ec7;border:none;border-right:1px solid #FFFFFF;}.all-cats .link{background:#328aae;border:none;}.all-cats .link:hover{background:#328aae;}.all-cats .link .title{color:#FFFFFF;border:none;}.all-cats .link .title:hover{color:#FFFFFF}.skin-box-bd .menu-list .menu .link:hover{background:#399ec7;}.skin-box-bd .menu-list .menu .link .title{background:none;color:#FFFFFF;font-weight:bold;}.skin-box-bd .menu-list .menu .link .title:hover{color:#FFFFFF}.popup-content{border:none;padding:0px;margin:0px;}.popup-content .popup-inner{border:none;padding:0px;margin:0px;background:#525252;}.popup-inner .cats-tree .fst-cat{background:#525252;border-top:solid 1px #FFFFFF;}.popup-inner .cats-tree .fst-cat:hover{background:#525252;}.popup-inner .cats-tree .fst-cat .cat-hd .fst-cat-name{color:#FFFFFF;}.popup-inner .cats-tree .fst-cat .cat-hd .fst-cat-name:hover{color:#FFFFFF}.popup-content .menu-popup-cats .sub-cat{background:#525252;}.popup-content .menu-popup-cats .sub-cat .cat-name{color:#FFFFFF;background:#525252;}.popup-content .menu-popup-cats .sub-cat .cat-name:hover{color:#FFFFFF;background:#525252;}.snd-pop-inner{height:auto;padding:0px;margin:0px;}.snd-pop-inner .fst-cat-bd{padding:0px;margin:0px;background-color:#9F9F9F;}.snd-pop-inner .fst-cat-bd .snd-cat-hd{background-color:#9F9F9F;}.snd-pop-inner .fst-cat-bd .snd-cat-name{color:#000000;}.snd-pop-inner .fst-cat-bd .snd-cat-name:hover{color:#000000;background-color:#9f9f9f;}

这么一大串，也不知道你什么布局。在你需要的半透明的地方添加一句话即可：
filter: alpha(opacity=50);opacity: 0.5;
