Blackbird Responsive change background to fixed

I have been searching endlessly to find the element.style line for changing the background to repeat fixed instead of repeat scroll.
I copied this rule from firebug where I changed the repeat to fixed and it works but when I add it to styling options custom css in blackbird theme options it doesn't work.
element.style {
background: url("http://psvintage.net/wp-content/uploads/2014/06/Background3_swirled2.jpg")

repeat fixed 0 0 rgba(105, 54, 54, 0);
}

this is the website I am working on for someone.

Help before I literally go insane!!!

 

Hello,

Paste the code given below in Custom CSS section
(Appearance -> Theme Options -> Styling Options -> Custom CSS) of your dashboard.

Code:

body {
background: url("http://psvintage.net/wp-content/uploads/2014/06/Background3_swirled2.jpg") repeat fixed 0 0 rgba(105, 54, 54, 0)! important;
} 

This will solve your issue.

 

I cannot say THANK YOU enough Piyush!
worked perfectly
