About the serif font
I think there is a mistake in the converting process of calibre.
Opening the stylesheet.css in my epub, I found 22 occurences of font-family, Times New Roman, sans-serif.
sans-serif provokes in fact a change of police.
I used
tweak_epub.exe (works with Wine; info for Linux users) to search and replace all occurences of
sans-serif with
serif, and this time it worked well (this is tricky). I got a real TNR with serif on my epub file.
question
can somebody give me the extra.css rule for increasing the space between the lines of text? I get nothing with line-height...
