I wish I had more to show, but the problem is simple. Following the github instructions, I place:
$.backstretch("path/to/image.jpg");
In the JS. It does apply the bg, but not in the body itself. At the end of the inner body it pastes:
<div class="backstretch" style="left: 0px; top: 0px; overflow: hidden; margin: 0px; padding: 0px; z-index: -999999; position: fixed; width: 1920px; height: 717px;"></div>
I tried the following as well:
$('body').backstretch("path/to/image.jpg");
It simply does not want to apply to the body. I need its magic on the body because I believe there's a chrome bug that will be resolved by doing such.
