Our webpage background images are having problems in FireFox as well as Safari in iOS on iPads/iPhones with white space showing up on the right side of the page.
The background images extend fine on other browsers but we're having difficulty not extending the full length of the browser on those browsers.
Take a look at our site on FireFox to see what I mean.
I added:
html,body
{
width: 100%;
height: 100%;
margin: 0px;
padding: 0px;
overflow-x: hidden;
}
into your CSS at the very top above the other classes and it seemed to fix your issue.
