How to auto resize a Salesforce Visualforce Page?

hi suraj,

You can do something like this:

HTML
<div id="boxContainerContainer">
<div id="boxContainer">
<div id="box1"></div>
<div id="box2"></div>
<div id="box3"></div>
</div>
</div>
CSS
#boxContainerContainer {
background: #fdd;
text-align: center;
}

#boxContainer {
display:inline-block;
border:thick dotted #060;
margin: 0px auto 10px auto;
text-align: left;
}

#box1,
#box2,
#box3 {
width: 50px;
height: 50px;
background: #999;
display: inline-block;
}
