Jetbook Mini - help with fb2 format

[jjm6383]

Is there anyone who could help me with fb2 formatting?

The books converted with Calibre have no centering, no blank lines to distinguish titles, no formatting that makes a book look good.

I've been working with html since the mid 90's when I bought a Rocketbook, and made my own books for fanfic. I've continued that with epub's, and gotten very good at formatting, so it looks with a "published" book.

I've downloaded Fictionbook Editor, but it's all about the structure of the fb2, and has no guide to formatting an fb2.

Thanks,
