Good Morning,
I am trying to set a background image for my website.

When using the body tag it is fine as it adjusts to fit different screen sizes.
body {
background-image: url(bg_main.gif);
background-position: center top;
background-repeat: no-repeat;
margin: 0px;
}
But I dont want to use the body, I have tried using a div and it only goes as far as the content in it.
#bkgd {
background-image: url(bg_main.gif);
background-position: center top;
background-repeat: no-repeat;
margin: 0px;
}

Can anyone help

regards

Daniel
