如何制作全宽下拉式响应菜单

Question

我无法将此菜单管理到全宽 这是我的代笔 http://codepen.io/anon/pen/xwDcb

我希望我的下拉菜单宽度从左到右为100％。我做错了什么

body {
background-color:#000;
}
.toggleMenu {
display: none;
background: #666;
padding: 10px 15px;
color: #fff;
text-transform: uppercase;
font-weight: bold;
width:100%;
}
.nav-full {
background:url(../images/nav-bg.png) no-repeat 0 0;
}
.nav-centre {
width:960px;
margin:0 auto
}
.nav {
list-style: none;
*zoom: 1;
}
.nav:before, .nav:after {
content:" ";
display: table;
}
.nav:after {
clear: both
}
.nav ul {
list-style: none;
}

我的HTML代码

<a class="toggleMenu" href="#">Menu</a>

<div class="nav-full">
<div class="nav-centre">
    <ul class="nav">
        <li><a href="index.html" class="active">HOME</a>

            <ul>
                <li><a href="#jquery-pagescroller-2">Indus Advantage</a>

Answer 1

你必须给导航中心类100％，现在它是975px或类似的东西，它包装你的列表元素。所以无序列表的100％是相对于导航中心元素的。

如果你想让导航菜单居中，那么导航中心的类位置：相对; 左：50％和保证金：左-511px。 （margin-left应该是无序列表的宽度）

我认为最好的解决方案是将下拉菜单从navi中删除。 所以它与其他列表无关。

像这样标记你的HTML：

<a class="toggleMenu" href="#">Menu</a>

<div class="nav-full">
    <div class="nav-centre">
        <ul class="nav">
            <li><a href="index.html" class="active">HOME</a></li>
            <li> <a href="#">Products</a></li>
            <li> <a href="#">Patents & Publications</a></li>
            <li> <a href="#">Partnering</a></li>
            <li> <a href="#">About Us</a></li>
            <li> <a href="#">Contact Us</a></li>
            <li> <a href="#">Careers</a> </li>
        </ul>

        <ul>
            <li class="under"><a href="#jquery-pagescroller-2">Indus Advantage</a></li>
            <li class="under"><a href="#jquery-pagescroller-3">Positioning and flexibility of products</a></li>
            <li class="under"><a href="#jquery-pagescroller-4">Pipeline</a>
        </ul>
        <ul>
            <li class="under"><a href="#">Overview</a></li>
            <li class="under"><a href="#">Exercise Physiology</a></li>
            <li class="under"><a href="#">Manufacturing & Quality Control</a></li>
        </ul>
        <ul>
            <li class="under"><a href="#jquery-pagescroller-0">Global Patenting Strategy</a></li>
            <li class="under"><a href="#jquery-pagescroller-1">Publications</a></li>
        </ul>
        <ul>
            <li class="under"><a href="#jquery-pagescroller-0">Enquiries - Product</a></li>
            <li class="under"><a href="#jquery-pagescroller-1">Enquiries - Business Partnering</a></li>
        </ul>
        <ul>
            <li class="under"><a href="#jquery-pagescroller-0">Vision & Values</a></li>
            <li class="under"><a href="#jquery-pagescroller-1">Conventional v/s the Indus Discovery Model</a></li>
        </ul>

    </div>
</div>

你现在只需要给li.under位置：绝对和其他，如何风格，应该清楚。
