First We create 3 Column HTMLStructure as Below.

<div class="wrapper">
<div class="leftcolm"> text content.... </div>
<div class="rightcolm"> text content.... </div>
<div class="midcont"> text content.... </div>

Now we will create CSS for 3 column structure of layout.

body { margin:0px; padding:0px; }
.wrapper { width:980px; margin:0 auto; }
.leftcolm { float:left; width:200px; background-color:#99FF99; padding:10px; }
.rightcolm { float:right; width:200px; background-color:#99FF99; padding:10px; }
.midcont { padding:10px; margin-left:230px; margin-right:230px; background-color:#CCCCCC; }

So this way our 3 column CSS and HTML Structure is ready, now we need to add sizing controls from user can change width of website layout.
Here is HTML code for Controls, Create UL sturcutre with 3 LI where we need to apply CSS class (switch_780, switch_980, switch_fluid) to anchor text.

<div class="controls">
<li><a href="#" class="switch_fluid">100%</a></li>
<li><a href="#" class="switch_980">980</a></li>
<li><a href="#" class="switch_780">780</a></li>

Here is CSS code for Controls, before that we need to create 3 icons for controls, icon images will apply by CSS this way.

.controls ul, .controls li { margin:0px; padding:0px; list-style:none; display:inline }
.controls li a:link, .controls li a:visited { float:right; display:block; height:15px; width:15px; text-indent:-9999px; overflow:hidden; margin-left:10px; }
.controls li a.switch_780 { background-image:url(images/icon_780.jpg); }
.controls li a.switch_980 { background-image:url(images/icon_980.jpg); }
.controls li a.switch_fluid { background-image:url(images/icon_fluid.jpg); }
.controls li{border:solid 1px #cc0000; width:14px; height:14px;}

JavaScript Code:

Now we need to create jQuery JavaScript, first include core jQuery Script, then we will create 3 different functions for 3 different control links, in that function we will apply “select” class in anchor so we can see which is active layout. and chance width of layout using “animate” function of jquery where we will define width of layout as per selection.

<script type="text/javascript" src=""></script>
<script type="text/javascript">
$("a.switch_780").click(function () {
$("div.controls a").removeClass("select");
$("div.wrapper").animate({width: 780}, 'slow', function() {;
$("a.switch_980").click(function () {
$("div.controls a").removeClass("select");
$("div.wrapper").animate({width: 980}, 'slow', function() {;
$("a.switch_fluid").click(function () {
$("div.controls a").removeClass("select");
$("div.wrapper").animate({width: '100%'}, 'slow', function() {;
