Reply To: How to make background image only appear on home and above fold?

Remove the background that you added, and then try adding this to your css manually –

.home.custom-background {
    background-image: url('http://mikemetcalfe.co/wp-content/uploads/2013/11/homepage-221.jpg');
    background-repeat: repeat;
    background-position: top left;
    background-attachment: fixed;
}

For the second question, I think you could just add a white (or whatever color you want) background to that particular div/section so the background image doesn’t show up.
