The attached epub has a little script that modifies the body margins of the ebook. It works flawlesly with the Calibre Ebook Editor, but in Calibre Viewer has an issue; once the epub is loaded, margins are not simetrical.

With the Viewer Inspector I was able to see that the issue is originated by the property "width" (for the element Body) added by Calibre. I tried a workaround by setting the property "width: auto" for Body (that disables the "width" added by Calibre), but that generated others problems (collisions with the properties "column-gap" and "column-width" added by Calibre, I think) and only the first page is showed correctly. So, my question is: how must I do in order that, if I modify margins with a script, Calibre Viewer shows them properly?

Many thanks in advance.
