Remove shadow between page and background

I'd like to make the background on my site white (which I learned to do thanks to your great answers in these forums, so thanks). The problem is when I change the background to white, there is a shadow around the page between the page and the background. I'd like the page to flow seamlessly into the white background without the shadow. Is there a way to do this?

Thank you!
Melanie

 

Paste this code in Custom CSS
Appearance > Theme Option > Styling Option > Custom CSS

Code:

.body_wrapper {
    box-shadow: none;
    }

 

Thank you for helping me resolve this!
