resizing css div in javascript

I have a CSS div defined as follows :
<div id="col-2" >

In some circumstances I want to change its width.
I have tried all the following within a javascript function:

document.getElementById("col-2").width= "900";
document.getElementById("col-2").resizeTo(900, 520);
document.getElementById("col-2").width.value= "900";
document.all.col-2.resizeTo(900, 520);
document.layers["col-2"].resizeTo(900, 520);

None of which have worked.

Within the stylesheet I initially had col-2 defined as an ID. Clutching at
straws I changed it to a class but that made no difference.

Can someone point out the right way to do it?
Thanks
Orson

Thats because its a style. So you need something like...

document.getElementById("col-2").style.width= "900";

(warning: I havent double checked this)

Blindly trying isn't the best approach :)

You should test whether
document.getElementById("col-2")
works at all. Try starting out with:
alert( document.getElementById("col-2") );
If that works, go on to changing the position.

Try:
document.getElementById("col-2").style.width = "900px";
That would use CSS to set the width.

Many thanks for the suggestions. I have finally got it all working.
Your suggestion to check my progress using alerts was instrumental in my
sorting it all out.
