height: 100%;
background: url('http://www.fg-a.com/wallpapers/geo-shapes-black-1280.jpg') no-repeat fixed center;
background-size: cover;
}
body {
width: 100%;
height: 100%;
position: absolute;
background-color: rgba(255, 255, 255, 0.35)
}

As you can see the background fits the whole page however the overlay does not. Why does it do that? I want the overlay to fill/cover the background. (In other words I want the overlay to fill the entire screen no matter the size of the screen because even if I resize the screen, the background fits the whole page yet the overlay is cut off.)
