So I put in the code on how you gave it to me, and it isn't doing anything. I've tried it with multiple image backgrounds. I put it in my custombnb/images folder and I still get nothing. What am I doing wrong. This is the code that I have:

body {
margin: 0;
font-family: verdana, arial, helvetica, sans-serif;
font-size: 25%;
color: #000000;
background-color: #e5edf5;
background-image: url(/domain/cart.bnbsoccer.com/html/includes/templates/custombnb/images/back2.jpg);
}
