CSS下拉导航

Question

我敢肯定这是简单的东西我失踪了......我的下拉菜单是打开的主导航，扩大它。这是我正在处理的页面的链接。问题在于App按钮下方的导航。

这里是我的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> 

这里是CSS：

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 {
