Question

以下导航栏适用于firefox，IE和Chrome。但是，在IE上，单击子菜单时显示的子子菜单未正确定位。它似乎与主菜单重叠。

我可以在不影响其他浏览器的导航栏布局的情况下为IE正确定位吗？问题出在navbar.css代码的最后一行。保证金顶部：-23px适用于除IE以外的所有浏览器。我在悬停时面临问题：

新闻和活动（运动日LInk和年日链接重叠常见问题解答（主菜单项）
招生（立即注册链接重叠招生链接本身）

顺便说一句，我正在测试IE9。

谢谢。

好的，我搞定了。一旦我添加了top：23px用于子列表样式，运动日和年度子菜单没有重叠新闻和事件。谢谢你。

#menu {
padding:0;
margin:0;
border:none;
margin-bottom:5%;


 /*font: 67.5% "Lucida Sans Unicode", "Bitstream Vera Sans", "Trebuchet Unicode MS", "Lucida Grande", Verdana, Helvetica, sans-serif;*/
    font-size:18px;
    font-weight:bold;
    position:relative;
    z-index:1;
}
#nav{
  padding:0;
    margin:0;
    border:none;
  list-style-type:none;
  float:left;
  height:25px;
  text-align:center;
  background:#ffcd05;
}

#nav li{ /*our program, about us, my child, event, etc..*/
     float:left;
     display:block;
     text-align:center;
     background:#f26739;
      width:126px;
      position:relative;  /*very important for good layout of submenus*/
     }
#nav li a{
    text-decoration:none;
    display:block;
    color:#ffffff;
    padding:0;
}
#nav li ul li{font-size:14px;}

#nav li:hover{
      background:#000000;
}
/* sublists style */
#nav ul{  /*lists that come under our program, event, etc...*/
position:absolute; /* very impt for good layout of submenus*/
left:0px;
top:23px;  /*sports day and annual day submenus will not overlap news and events*/
display:none;
padding:0;
}

/*--- Hide Sub Sublists ---*/
#nav li:hover ul ul {display:none;}

/*--- Sublevel UL's display and position on hover ---*/
#nav li:hover ul{display:block;}

#nav li li:hover ul {margin-left:110px; margin-top:-23px;display:block;}
