How to have a fixed background.

[cutmaster]

Hi,
I'm asking me how to have a fixed background with things scrolling on it, instead of having my background repeated verticaly ?
I've tried the following without success :

Code: Select all

body {
  background-color:#333333;
  background-image:url("background.png");
  background-repeat:repeat;
  background-attachment:fixed;
  color:#ffffff;
  font-family:Verdana,Arial,Sans-serif;
  font-size:12px;
}

Any idea ?
