i would put the page holder in my css as well and include everything inside the body in it?
Yes.
Referencing the Dynamix Labs site:
The body will have a background property that sets the repeating orange tones.
(smoovo provided the css below)
The page container or content holder element will have a background property that uses a translucent white image.
(this css also provided by smoovo, and image recommendation is good)
Optional
You could use the css2 opacity property to change a solid white background to semi-transparent. Then no image will be needed at all.
NOTE: This method will require you to use the filter property for IE. Here is an example:
Code:
div.container {
background-color:#fff;
opacity:0.85;
filter:alpha(opacity=85);
}
