```
@media screen and (min-width: 800px) {
    html {
        background: url('/img/ground.png') no-repeat center center fixed;
        -webkit-background-size: cover;
        -moz-background-size: cover;
        -o-background-size: cover;
        background-size: cover;
        }
    }

```

If I will use smartphone with screen less than 800px, image will downloaded to my device or not?
