问题
I am trying to create a page similar to Google's homepage. It is to have a centrally located input box and a div on top of the page displaying links. I also want the page to resize itself dynamically if I change the size of the browser window. I have achieved partial success using yui2 grid css and a table. Here's a snippet:
<body>
<div id="doc3">
<div id="hd"><a style="float:left" href="link1.com"> link1</div>
<div id="bd" style="display: table; height: 400px;">
<div style="display: display: table-cell; vertical-align: middle">
<input name="searchbox" value="searchinput" size="40" />
<input name="submit" type="submit" value="search />
</div>
</div>
</div>
</body>
The only issue with this html is that the page doesn't dynamically resize upon resizing the browser window. Is there a better way of doing this ?

You can use jQuery to set it to perfectly.
jQuery
$(window).resize(function() {
var wh = (($(window).height()-$('#center').height())/2)+'px';
var ww = (($(window).width()-$('#center').width())/2)+'px';
$('#center').css({
top: wh,
left: ww
});
}).resize();
CSS
#center {
border: 1px solid black;
position: absolute;
width: 50px;
}
If you don't care about perfectly vertically centered, you could do:
#center {
border: 1px solid black;
margin: 0 auto;
position: relative;
width: 50px;
top: 45%; /* or whatever % looks 'right' */
}
