Please forgive this newby question, which I'm sure has been discussed before.

My goal is to transfer my manuscript of quotes for distribution via Kindle.

I first formatted the text and created a pdf that can be used for viewing on the computer.

Following suggestions read on this forum, I then used CALIBRE to convert the rft manuscript to AZW3. The problem is line spacing. Attached you can see:
a. sample from the pdf, with proper line spacing
b. sample from the reformatted rtf, still respecting the line spacing design
c. photo of Kindle screen that shows wrong line spacing.

I do read in the forums that I need to play with the CSS codes for text height and line height to create the design I desire. My questions at this point are:
1. where are these codes in the rtf file? how can I view them? I can see the pilcrows but nothing more than that.
2. what program should I use to try to edit those?

thank you.
