How Do You Add Borders Around Adds?

[Dj Smuggla]

I've made some border images that i want to put around my adds, but not shore the best way to do it.
I thort i could maybe make a div called adds, then in the additional css part put something like:

.adds {
        border-top: url(http://Link To Top Border); 
	border-left: url(http://Link To Left Border); 
	border-right: url(http:// To Right Border);
	border-bottom: url(http://Link To Bottom Border);

Is that right & would that be the best way to do it?
