I have used calibre for a while but just start to use it to convert ebooks.
I have a programming book in html format (
http://www.diveintopython.org/). As all other programming books, it contains code examples that are in fixed width fonts. when calibre convert the book, they are not long fixed width font. How do I make ePub use different fonts for different part of the book?
I did a few searches in the forum, but could not use a good search term to find the answer to my question.
