Background image width not 100% on iPad

Question

My background images have not been spanning the full width of the browser when viewed on an iPad. This has happened more than once now, so it must be in the way I\'m writing

Answer 1

Pretty sure iPad screen width is 1024px. Is that set anywhere?

body{
 min-width:1024px;
}

Note: I've not got mine on me to test.
