菜单悬停应在当前站点上停止

Question

我希望悬停（Lavalamp-red，这是一张图片）停在用户当前所在的网站上。

如果可能，我还想更改当前网站上的悬停颜色以及字体颜色。

.column {
    margin: auto; 
    width: 30%; 
    padding: 0 2em; 
    min-height: 1%; 
    position: relative;
}

.column *, *:after, *:before { -webkit-box-sizing: border-box; -moz-box-sizing: border-box; box-sizing: border-box; }

.container {
   height: 2%; 
   margin: 7% auto;
   width: 957px;
   text-align:justify;
}
.container>ul>li>a:hover {
     margin-bottom:20px;
}

#nav,#nav ul {
    list-style: none outside none;
    margin: auto;
    padding: 0;
}
#nav {
    background: url('menu_bg.png') no-repeat scroll 0 0 transparent;
    clear: both;
    font-size: 12px;
    height: 58px; 
    padding: 0 0 0 9px;
    position: relative;
    width: 957px; 
}
#nav ul {

    border:1px solid #eeb422; 
    border-radius: 0 5px 5px 5px;
    border-width: 0 1px 1px;
