How to convert "Book A" using css, formatting, fonts 1:1 -> "Book B"?

[Mr.Husky]

Hi everybody.

I have a "Book A". I like a publisher's paragraph spacing, css style, custom fonts etc. How to convert another book using these data 1:1 with Calibre? Is it possible? Thank you for your attention.

Spoiler:

Sorry for my poor English, at least i tried

Play matchup .

Since many books DO NOT use a common stylesheet (or the coders ignore House Rules mapping)
Yo need to make the proper styles do the same.
1) make the body class match
2) make the indented paragraph style match
2b) view and adjust Italic / bold span class as needed if they do not inherit nicely.
3) make First Paragraph, Chapter title match (if you care about it that far)
