Question

示例：http://www.studentbridges.org/new/

我试图让我的导航栏跨越网页的顶部，我让Nav的div跨越网页，但当我将导航菜单放在div中时，下拉停止工作，无论我做什么，链接都不会居中（text-align：CSS中的中心和标题中的标记不起作用）。

这是我的代码：

导航

.access {
clear: both;
display: block;
float: left;
margin: 0 auto 6px;
width: 100%;
}
.access ul {
font-size: 16px;
list-style: none;
margin: 0 0 0 -0.8125em;
padding-left: 0;
}
.access li {
float: left;
position: relative;
}
.access a {
color: #eee;
display: block;
line-height: 3.333em;
padding: 0 1.2125em;
text-decoration: none;
}
.access ul ul {
display: none;
float: left;
margin: 0;
position: absolute;
top: 3.333em;
left: 0;
width: 188px;
z-index: 99999;
}
.access ul ul ul {
left: 100%;
top: 0;
}
.access ul ul a {
background: #EAC57E;
border-bottom: 1px dotted #ddd;
color: #F7E7C6;
font-size: 14px;
font-weight: normal;
height: auto;
line-height: 1.4em;
padding: 10px 10px;
width: 168px;
}
.access li:hover > a,
.access ul ul :hover > a,
.access a:focus {
background: #DBAA4A;
}
.access li:hover > a,
.access a:focus {
background: #DBAA4A; /* Show a solid color for older browsers */;
color: #F7E7C6;
}
.access ul li:hover > ul {
    display: block;
}
.access .current-menu-item > a,
.access .current-menu-ancestor > a,
.access .current_page_item > a,
.access .current_page_ancestor > a {
font-weight: bold;
}

Top Nav DIV：

div#topnav

{
margin: 0px;

overflow: hidden;

width: 100%;

height: 50px;

background: #8D1D1D;

}

对此问题的任何意见都将非常感谢！

Answer 1

你走了：

http://jsfiddle.net/UjEd5/

实际的导航选项本身不同，但CSS使用相同的ID /类你正在使用的结构。

你会注意到我改变了

<div class="access">

到

<div class="topmenu">

如果您为“topmenu”DIV和“access”UL分配相同的宽度，它将居中栏中的导航。

希望这有帮助！
