CSS absolute position content area not growing

I am trying to create HTML design. I am stuck in one question. CSS n HTML structure is the image I attached here. I want the footer to be at the bottom of the page, where the content area when growing should push the footer. But if there is no content, the content area should be up to the footer. in fact, the content area approaches the area of ​​the header and footer. I do not know if I structured it correctly.

enter image description here

    <html xmlns="http://www.w3.org/1999/xhtml">
    <head>
<style>
html, body { height:100%;}
body {
    background: #EBEBEB;
    margin: 0px;
    padding: 0px;
}
#wrapper {
    width:100%;
    height:100%;
    margin: 0 auto;
    position:relative;
}
#header {
    width:100%;
    height:147px;
    background:#999;
    border-bottom:solid 5px #ddd;
    position:absolute;
}
#footer {
    bottom:0;
    width:100%;
    height:170px;
    position:absolute;
    background-color:#ccc;
    border-top:solid 5px #ddd;
}
#contentArea {
    width:300px;
    max-height:100%;
    position:absolute;
    z-index:999;
    left:0;
    right:0;
    top:0;
    bottom:0;
    margin-left:auto;
    margin-right:auto;
    margin-top:120px;
    margin-bottom:100px;
    background:#FFF;
    border:solid 1px red;
}
</style
</head>
