Footer won't stay at bottom below content despite sticky footer - footer

Question

I can't seem to get the header and footer to span across a mobile device such as iPhone, and the footer won't stick to the bottom. I've tried a meta code such as this:
My CSS mobile:
#charset "utf-8";
#logo {
left: 5%;
}
#navMenu {
position: relative;
left: 5%;
}
#content {
position: relative;
width: 95%;
height: 600px;
left: 2px;
right: 2px;
}
#footer {
position: fixed;
bottom: 0;
z-index: 5;
}
I've added this to the HTML meta:
meta name="viewport" content="width=device-width, height=device-height, initial-scale=1.0 maximum-scale=1.0,
Here is my desktop CSS incase something may override my mobile:
#header {
position: absolute;
top: 0px;
left: 0px;
width: 100%;
height: 45px;
z-index: 1;
box-shadow: 0px 0px 0px 1px rgba(82, 82, 82, 0.2);
background-color: rgba(234,234,234,1);
}
#navMenu {
position: absolute;
left: 55%;
top: 55px;
width: 325px;
height: 39px;
z-index: 3;
}
#logo {
position: absolute;
left: 20%;
top: 95px;
width: 300px;
height: 85px;
z-index: 1;
}
#pageLocation {
position: absolute;
right: 20%;
top: 240px;
width: 69px;
height: 25px;
z-index: 5;
color: rgba(50,153,204,0.1);
}
#content {
position: absolute;
right: 20%;
top: 270px;
height: 600px;
width: 60%;
padding: 10px;
margin-bottom: 50px;
z-index: 2;
border-bottom-color: rgba(50,153,204,0.2);
border-bottom-width: thin;
border-bottom-style: solid;
border-radius: 5px;
background-color: rgba(204,204,204,.1);
border-right-width: thin;
border-right-style: solid;
border-right-color: rgba(204,204,204,0.2);
border-left-width: thin;
border-left-style: solid;
border-left-color: rgba(50,153,204,0.2);
box-shadow: 0px .5px .5px .5px #333;
}
#footer {
position: absolute;
alignment: center;
bottom: 0;
left: 0;
width: 100%;
height: 50px;
z-index: 1;
text-align: center;
padding: 2px;
font-size: 12px;
line-height: 2px;
box-shadow: 0px 0px 3px 0px #333;
background-color: rgba(204,204,204,.7);
}
I've tried sticky footer techniques with no luck. I've gotten the footer with this method to stick to the bottom, but it just overlaps content when I scroll back up. Please help, this is very frustrating to get a simple iPhone/android capable footer that sits at the bottom of the page.
