I have searched the whole internet for a solution to this and none of the explanations are complete or it could be i do not know enough css..but i want to create a drop shadow around the border of my webpage

First off i don't actually have a border per say i need to create it...since this is a template monster template there isnt a visible border on the template

This is what i want to do i want to have the drop shadow like this website

http://www.echo-electronics.com/

I do not have to have the rounded corners like that, i really just want the border and the dropshadow


Im pretty sure that this is done with css and images somehow...but i do not know the css code and how to position the images with the code... and there are no good explanations anywhere that i could find on the internet they are to vague and expect you to know css really well

Id appreciate any help at all,

thanks in advance
