Sorry for appearing dumb about these things but do you mean the stylesheet.css
I loaded a correct epub in Sigil 0.2, copied the stylesheet.css info to Notepad then did the same with one of my epubs which has the white spaces, compared the info between the two but they both look similar.
Could someone post a stylesheet.css of how it should look, then I could learn from that
