How to create a border around a website like this?

[pookeyblow]

Hi guys,

New to CSS, and i have a question:

How do I create a fixed border around my website like they have done here?: http://www.sagmeisterwalsh.com

I've tried with:

body, html {
    margin: 0px;
    padding: 0px;
    border: 6x solid #ac9cff;
    width:100%; height:100%
}

but it doesn't seem to work. It's not fixed either.

Any suggestions. I believe this is easy to do, right?
