Full Width Background images?
I was wondering what the best way to get a full page width background image would be? Where it would expand / contract as the browser does. Two example sites where you can see what I mean are: http://www.shopify.ca/ and https://www.airbnb.ca/, as well as many others. If you look at the background image (not the entire site background, but just a small portion of it) they have it display nicely in the back and as you move the browser window, adjust size, etc, it stays intact (even though it may contract, etc).
