CSS Borders

I have a light gray box, with a dark gray 1px solid border. I would like to add a 1px white highlight (bevel) on the left/top (inside the border). Id really like to avoid wrapping everything in a second div, but im not sure if it's possible with the border properties?

This is what I have working have so far, except the 2nd groove color is too dark as I would like it to be the same as the bottom/right color.

border-left: 2px groove #FFFFFF;
border-top: 2px groove #FFFFFF;
border-right: 1px solid #B1B1B1;
border-bottom: 1px solid #B1B1B1;
background-color: #EAEAEA

Can't have two border properties for one border, so you'd have to wrap it, unless that groove thing is working for you.

Yeah I finally wrapped it. It wasn't as messy as I thought it would be. My code's actually a little more organized now as I have :

.contentbox - outerborder, margins, bg color
.content - inner border, padding, text

Thanks.
