Boxed Layout – How to add white solid border around the whole box.

Hi, I’ve been trying to mess with the quick CSS and playing around with Firebug but can’t seem to get it to work. I am new to learning CSS but doing my best. I am currently using a boxed layout of my page and I want to add a white solid border – 1px width around the whole outer edge. I already have the all four sides margined using this code already.

.boxed#top {
margin: 20px auto;
}

** Also I’d like to add a white glow effect if possible, I’ve been messing around with this code but any input is appreciated.
// For glow effect
box-shadow: 0px 0px 10px;

Any help is appreciated. Thanks!
