WPFolio — How to make the body transparent?

Hi,

I’m trying to edit the css stylesheet in order to have a transparent body to show a background image for the full page. Since each theme is written a little differently i’m having a hard time figuring out what i need to edit.

example:
/* BEGIN user editable area */
body{
/* font-family: ($WPFolio_body_font)*/
/* color: ($WPFolio_body_color)*/
padding: 5px;
}
.container{
/* color: ($WPFolio_body_color)*/
/* background-color: ($WPFolio_foreground_color)*/
margin-top: 30px;
width: 960px;
margin: 0px auto;
text-align: center;
padding: 0px;

i thought to change the background: and color: to “transparent” but that doesn’t do the trick. anyone have an idea?

thank you!
