Essentially what I am trying to find out is how the plugins use the predetermined theme background. In my instance I have installed the "Set Sign-In Page as Landing Page" plugin and I'm happy with it... however ideally I would like it to have the sites index page as the background while leaving the actual plugin as foreground.
I personally would prefer the sign-in page not be a solid color with the widget, but rather a background of the owners site(out of focus), with the widget overlay until the user signs in or registers.
Is there a way I can do this on my own. I'm not a true coder but I am attempting to learning, and I would not mind trying to make this happen with some guidance.
I have attached an image to better help explain the out come I am after.
