Hello there ..

I am setting up a website for my client, but i got some troubles with the wallpaper

Here is the website:
http://www.lindenskov.net/

Here is the CSS:
http://lindenskov.net/wp-content/the...ress/style.css

I want to have a wallpaper, or something like a left and right sidebar to place some pattern wallpaper (like now).. It is a bit boring with all that black color ..
It needs to fit the screen regardless the screen resolutions

Thank you for your time!
