How do I seperate posts in Wordpress?

I'm still working on wordpress, and I'm trying to put the posts in seperate boxes like the TIGA-06 theme http://themes.wordpress.net/testrun/?wptheme=66 . how can i make my page like that? this is what mine looks like right now http://www.5thround.com/wordpress/

 

here's what you need to do...
edit your stylesheet here:

#post {
padding-left:5px;
padding-right:5px;
margin-top:1px;
margin-bottom:1px;
border: 1px solid #cccccc;
}

Code (markup):

 

just tried that, still having the same issue... maybe the color should change?

 

I can't get a </div> at the end of each post, that's why it's not seperating. I've been looking at the code for 2 days, I have no idea how to get that end </div> after each post.

 

it looks like you got it fixed?

 

LOL yea, thanks I got it but I ran into another problem... If you notice the date has dissapeared from every post except for the first post. Any idea how that happens?

 

Wordpress does not like <div> in posts. You just can't do it.
