Make most recent post a div and the others span

Hi,

I need to put the first post in a div and the others (3) in spans; I am currently applying a different style (from the other posts) to the most recent post.

I was thinnking of something along the lines of using an offset, much like the way I am applying different styles to posts; I don’t know how to make wordpress understand what I want to do but I was thinking like this:

if ($post == $post[0]){

<div stuff>
etc
</div>

} else {

<span stuff>
etc
</span>

}

I hope that makes some sort of sense, if you understand what I’m trying to do could you please help.

Thanks
