/* Basic Styling for HTML and BODY Sections of a File */
	border-width:	0;
	height:	100%;
	margin:	0;
	orphans:	1;
	padding:	0;
	widows:	1;
}

If I pull the ", html" bit off (leaving just body), the Viewer behaves normally. Well, more normally. Without including "html," the Viewer's margin settings override the book's css margin settings. With the "html" settings, the book's margins apply, but the right and bottom margins are ignored. Unfortunately, I'm not knowledgeable enough to know if that's correct behavior.

Forget html. It's not needed. And height: 100%; could be a problem. I have no idea what it's doing in the body and html CSS. It's not essential at all. Also, you don't need border-width and padding.

This is the body code I use and it works perfectly in the Calibre viewer and on a Kobo in both ePub and KePub.

body {
  widows: 1;
  orphans: 1;
  margin-top: 0;
  margin-right: 0;
  margin-bottom: 0;
  margin-left: 0;
  text-align: justify;
}
