CSS drop down navigation - html

Question

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.

Here is my 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>About Us
<ul>
<li>Who We Are</li>
<li>News</li>
</ul></li>
<li>How It Works</li>
<li>Facts</li>
<li>Tools</li>
<li>Testimonials</li>
<li>News</li>
<li>Brand Name Awards</li>
<li>Contact</li>
</ul>
And here is the 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;
}

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;
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;
