I would like to be able to change my webpage background image according to the screen resolution the user uses so:
if screen resolution is greater than or equal to 1
Set body css to :
body { background: url(../img/background.jpg) no-repeat center center fixed #000; -webkit-background-size: cover; -moz-background-size: cover; -o-background-size: cover; background-size: cover;
}
