I put together a very basic example for you of how you can accomplish this design using basic floats.
<style type="text/css">
<!--
#container {
background-color: #7cc576;
height: 426px;
margin: 0 auto;
width: 1080px;
}
#cols {
overflow: hidden;
}
#cols .col {
float: left;
height: 550px;
}
#cols #left {
background-color: #00bff3;
width: 317px;
}
#cols #center {
background-color: #448ccb;
width: 544px;
}
#cols #right {
background-color: #605ca8;
width: 219px;
}
#footer {
background-color: #f68e56;
}
//-->
</style>
<div id="container">
<div id="header">
Header
</div>
<div id="cols">
<div class="col" id="left">Left Column</div>
<div class="col" id="center">Center Column</div>
<div class="col" id="right">Right Column</div>
</div>
<div id="footer">Footer</div>
</div>
The background colors are added just to show the different blocks. To center this design, I used the code ‘margin:0 auto’ on the container div. Feel free to ask any questions
