background image/gradient

[ZiG]

hey, i'm not very good at this so maybe someone could help me out;
i'm trying to make a gradient background that adds a shadow effect to the border of the "page background", very similar to the way vbulletin.org has the gradient effect on both sides of the page (pretty much exactly the same thing actually)

my page is located here:
http://www.rdyup.com/

i am trying to make one for both the light and dark themes (switch on the bottom left of the website)

maybe someone can help me with this? thank you.

nevermind, i figured this out myself...i made the graphic in photoshop and here are the css properties for anyone interested:

background-image:
url(/forums/images/yourbrackground.gif);
background-repeat: repeat-y;
background-attachment: fixed;
background-position: 50% 75%;

holds the background image in place, and repeats it down the entire page.
