Problem changing margins on an ePub
I normally have no problem changing the margins on commercial ePub's, but I've got one right now that's vexing me. Normally it's a simple matter of editing the CSS or, if it has one, page-template.xpgt file. I've done that this time and the ePub still has large margins. I also tried running it through Calibre and they didn't change.
Any ideas on where else in the file I might have to look to be able to edit the margins?
