Problem with some titles that have major margin issues

[LadyKate]

I have some titles that have major margin issues in Calibre viewer. The margins seem to be off the page and change with every page (getting worse). For some reason things look ok in the editor and horrid in the viewer.

Any suggestions on how best to handle this problem is welcome. Can't upload a copy of this as it is not my personal work.

Cascading styles, instead of maintaining a Block

Validate the Stylesheet at W3C, there is probably a colon or semicolon in the wrong place(very hard to spot visually)

Would that be an issue with a retail book? Just curious as this is a retail book that I converted to epub.

You would not believe some of the stuff I see in some 'Retail' books.
(Retail, simply means that it was sold, not home made )
Even BPH crank out cr*p because they hire coders that can't even follow 'House Stylesheet' rules.

Even Baens (conversion?) EPUBs include an additional nested Div for each chapter split, so by the 10th chapter, the CODE is indented half way across the screen. I have a 'BaenDeDiv saved search&replace that I run against all files (sometimes as many as 50 passes). The book looks fine. The code was bloated and Ugly.

I suspect you have a bad case of nested Blockquote (they should have used a Div (or nothing) )

Amateurs (coders):
They come in all kinds. Top Quality to 'Not a clue"

If the book won't validate (with no red error level), I can figure where they fall.
Validate, is only the first step
Next is getting rid of code that only appears to work (Calibre class viewers tolerate lots of cr*p that many devices abort or lockup on)
stuff like:

<p></p>
<span> </span>

(somebody's REGEX was wrong )

Ducks I use Diapdealers "Diap's Editing Toolbag" to delete them.

Action: delete
tag name: div
Having the attribute: id
whose value is: calibre_pb_\d+
and tick the regex box.

Get's rid of them in one pass.

Thanks for that tip. I have been doing it the other way so long, that I never thought to revisit newer tools

I have come across the same problem, I think it is a bug in the Calibre ebook-viewer and so I've submitted a bug report.

This problem only seems to occur when all of these conditions exist:

* The "Text layout in paged mode --> Override the page margin settings specified in the book" option is un-ticked in the ebook-viewer preferences.

* The publisher hasn't specified a @page margin style in the book's stylesheet.

Edit:
* The publisher has used a percentage value for the body margin in the book's stylesheet.

Easiest work-around is probably just to tick the "Override the page margin settings specified in the book" option.

(Edit: The problem I experienced has been fixed in Calibre 2.64, not sure if it is quite the same problem the OP had though.)
