Is it possible to somehow make an adaptive background without meta?

Question

Adaptive design

You can somehow make the background completely fill the screen, using horizontal and vertical scrolls and without a white line at the bottom (as in the screenshot). To just shrink everything inside, depending on the screen size? Or is it impossible to do this without writing meta for each screen size?
I've tried all this, it doesn't help. Maybe there is something else?

background-size: 100px 100px;
    background-size: contain;
    background-attachment: fixed;
    max-width: 100%; 
    background-size: 100% auto;
    background-size: cover;
    -o-background-size: cover;
    -webkit-background-size:cover;
    -moz-background-size: cover;
    background-position: center center;
