CSS 下拉导航

问题描述

我确定这是我缺少的一些简单的东西...我的下拉菜单正在主导航中打开，并扩大了它.这是我正在处理的页面的链接.问题在于应用按钮下方的导航.

I'm sure this is something simple I'm missing... My drop down menu is opening within the main navigation, widening it. Here is a link to the page I'm working on. The issue is with the navigation below the App buttons.

这是我的 HTML:

 <div class="container-fluid">
         <div class="section-title2 text-center">        
                <div class="navigation">
                    <label for="show-menu" class="show-menu">Show Menu</label>
<input type="checkbox" id="show-menu" role="button">
<ul >
    <li><a href="#">About Us</a>
    <ul>
    <li><a href="about.html">Who We Are</a></li>
    <li><a href="news.html">News</a></li>
    </ul></li>
    <li><a href="HowItWorks.html">How It Works</a></li>
    <li><a href="FactsStats.html">Facts</a></li>
    <li><a href="ParentingTools.html">Tools</a></li>
    <li><a href="testimonials.html">Testimonials</a></li>
    <li><a href="news.html">News</a></li>
    <li><a href="awards.html">Brand Name Awards</a></li>
    <li><a href="contact.html">Contact</a></li>
</ul>

这是 CSS:

.navigation{
margin-right: auto;
margin-left: auto;
width: 100%;
background-color: #0f9cde;
position: absolute;
display: block;
margin-bottom: 15px;
z-index: 1000;
top: 735px;
margin-left: -15px;
}
/*Strip the ul of padding and list styling*/
.navigation ul{
list-style-type: none;
margin: 0 auto;
padding: 0;
position: relative;
z-index: 10000;
text-align:center;
}

/*Create a horizontal list with spacing*/
.navigation li{
display:inline-block;
margin-right: 0px;
background-color:#0f9bde;

}

/*Style for menu links*/
.navigation li a {

min-width: 189px;
height: 50px;
text-align: center;
line-height: 50px;
font-family: 'Maven Pro', sans-serif;
font-size:18px;
color: #fff;
width:100%;
background-color: #0f9cde;
text-decoration: none;
display:block;

}

/*Hover state for top level links*/
.navigation li:hover a {
color: #f7a800;
text-decoration: underline;
}

/*Style for dropdown links*/
.navigation li:hover ul a {
background: #f7a800;
color: #ffffff;
height: 40px;
line-height: 40px;
z-index: 10001;
}

/*Hover state for dropdown links*/
.navigation li:hover ul a:hover {
background: #fff;
color: #f7a800;
}

/*Hide dropdown links until they are needed*/
.navigation li ul{
display: none;
z-index: 10001;
}

/*Make dropdown links vertical*/
.navigation li ul li {
display: block;
float: none;
}

/*Prevent text wrapping*/
.navigation li ul li a {
width: auto;
min-width: 100px;
padding: 0 20px;
}

.navigation ul li:hover ul{
display:block;
}

/*Display the dropdown on hover*/
navigation ul li a:hover  {
display: block;

}

推荐答案

你要给选择器添加一个 position:absolute .navigation li ul

You have to add a position:absolute to the selector .navigation li ul

.navigation{
margin-right: auto;
margin-left: auto;
width: 100%;
background-color: #0f9cde;
position: absolute;
display: block;
margin-bottom: 15px;
z-index: 1000;
margin-left: -15px;
}
/*Strip the ul of padding and list styling*/
.navigation ul{
list-style-type: none;
margin: 0 auto;
padding: 0;
position: relative;
z-index: 10000;
text-align:center;
}

/*Create a horizontal list with spacing*/
.navigation li{
display:inline-block;
margin-right: 0px;
background-color:#0f9bde;

}

/*Style for menu links*/
.navigation li a {

min-width: 189px;

font-family: 'Maven Pro', sans-serif;
font-size:18px;
color: #fff;
width:100%;
background-color: #0f9cde;
text-decoration: none;
display:block;

}

/*Hover state for top level links*/
.navigation li:hover a {
color: #f7a800;
text-decoration: underline;
}
