background-size: cover doesn't work for height

Question

I have to make a wallpaper and stretch it to the screen, the CSS3 cover doesn't really help VERTICALLY

background-size: 100% 100%;

I saw some post but they didn't work with me.

This is my code :

background-image: url('/wallpapers/img.jpg');
background-repeat:  no-repeat;
-webkit-background-size: cover;
-moz-background-size: cover;
-o-background-size: cover;
background-size: cover;

Any Idea please ?

Answer 1

you have some syntax errors, the right code is

body {
    background-image: url("/wallpapers/img.jpg");
    background-size: cover;}
