How can i add a white boarder to this?

#container {
width: 800px ;
margin-left: auto ;
margin-right: auto ;
background-color: #CCC;

}


I want to make the container boarder look similar to this website:

Though without using an image

A simple white border would be something like this:
A border with curved corners and such is a bit fancier, and requires CSS and multiple images. See these examples:

Rounded corners and shadowed boxes

Thanks! Exactly what i wanted =)
