Here's a good solution, in my opinion the easiest one. It looks clean and it doesn't need wrapper div.

Demo

HTML

<body>

<div id="left_container">
    <div id="left">
        left content
    </div>
</div>

<div id="center">
    center content
</div>

<div id="right_container">
    <div id="right">
        right content
    </div>
</div>

</body>

CSS

#left_container {
  width:50%;
  float:left;
  margin-right:-480px; /* minus half of the center container width */

  /* not important */
  height: 200px;
}
#left {
  margin-right:480px; /* half of the center container width */

  /* not important */
  background: #888;
  height: 600px;
}
#center {
  width:960px; /* size of the fixed width */
  float:left;

  /* not important */
  color: #FFF;
  background: #333;
  height: 500px;
}
#right_container {
  width:50%;
  float:right;
  margin-left:-480px; /* minus half of the center container width */

  /* not important */
  height: 300px;
}
#right {
  margin-left:480px; /* half of the center container width */

  /* not important */
  height: 300px;
  background-color: #888;
}

enjoy!

There are several solutions to this, probably the post popular of which is the Holy Grail method. It's a little above my head, but these links explain it pretty well.

http://matthewjamestaylor.com/blog/perfect-3-column.htm

I would start with A List Apart's article. Good luck.

After re-reading it, I think this is what I would do:

HTML

<div id="header">
</div><div id="container">
    <div id="center" class="column"></div>
    <div id="left" class="column"></div>
    <div id="right" class="column"></div>
</div><div id="footer"></div>

CSS

body {
    min-width: 550px;      /* 2x LC width + RC width */
}
#container {
    padding-left: 200px;   /* LC width */
    padding-right: 150px;  /* RC width */
}
#container .column {
    position: relative;
    float: left;
}
#center {
    width: 100%;
}
#left {
    width: 200px;          /* LC width */
    right: 200px;          /* LC width */
    margin-left: -100%;
}
#right {
    width: 150px;          /* RC width */
    margin-right: -150px;  /* RC width */
}
#footer {
    clear: both;
}
/*** IE6 Fix ***/
* html #left {
  left: 150px;           /* RC width */
}

You'll need to adjust some of the dimensions, but the inline comments should help with that. So there you have it. The Holy Grail Layout.

Is this helpful?

CSS Only Demo

jQuery Demo(Cross Browser Compatible)

<div class="wrap">
    <div id="pixelLeft">&nbsp;</div>
    <div id="bannerCenter">
      <img src="images/mybanner.png" />
    </div>
    <div id="pixelRight">&nbsp;</div>
</div>
<div style="clear:both;"></div>

*{
    margin:0;
    padding:0;
}
#bannerCenter{
    background:#ffffd;
    width: 500px;
    float:left;
}
#pixelLeft{
    background:#999;
    width: calc(50% - 250px);
    float:left;
}
#pixelRight{
    background:#999;
    width: calc(50% - 250px);
    float:right;
}

#bannerCenter,#pixelLeft,#pixelRight{
    height: 400px;
}

You can use jQuery instead of using calc(50% - 250px); to make it compatible for older browsers.

$(document).ready(function() {
    $(window).on('resize', function() {
         $('#pixelLeft, #pixelRight').css('width',($('body').width()-$('#bannerCenter').width())/2);
    }).trigger('resize');      
});

Update: June 2018

Added flexbox solution for same problem.

*{
    margin:0;
    padding:0;
}
.wrap {
  display: flex;
}
#pixelLeft, #pixelRight{
  display: flex;
  flex:1;
}
#bannerCenter{
    background:#ffffd;
    min-width: 500px;
    display: flex;
    flex: 1;
}
#pixelLeft{
    background:#999;
}
#pixelRight{
    background:#999;
}
#bannerCenter,#pixelLeft,#pixelRight{
    height: 400px;
}

<div class="wrap">
    <div id="pixelLeft">&nbsp;</div>
    <div id="bannerCenter">
      <img src="images/mybanner.png" />
    </div>
    <div id="pixelRight">&nbsp;</div>
</div>

<body>
  <div style="   width: 200px;    float: left;    background: red;    height: 100px;">Left</div>
 
  <div style="    float: right;    width: 200px;    background: red;    height: 100px;">Right</div>
   <div style="    background: blue;  margin:0 auto; height:100px;">Center content goes here</div>
</body>

Here is simple trick through html and css only to do such a layered structure and it will keep middle layer in center even if you will resize browser.
