Issue converting ePub to MOBI

Ramses505 · 05-19-2021, 06:58 AM

I have an ePub file where I have adjusted the line spacing by editing an entry in the 'stylesheet.css' from this;
.calibre5 {
font-family: "Calibri", "sans-serif";
font-size: 1.33333em;
}

to this;
.calibre5 {
font-family: "Calibri", "sans-serif";
font-size: 1.33333em;
line-height: 2.0em
}

Adding the line-height modifier and checking that the text in the file preview looks something like I am after. However, after converting the file to a MOBI format, the spacing of the lines in the paragraghs of text are not changed from how they were before I adjusted them in the ePub file. When I go back to the ePub file, my edits show and the paragraph text spacing still looks correct as per my edits.

What is happening and how can I maybe get things to look the way I need them ?

Thanks for reading and any helpful suggestions.

Does the Kindle accept line heights of greater then 1.2?

Thanks very much for the replies. I am grateful but confused. Kovid states (and I have seen he has stated it several times in answer to different questions) that mobi files do not have the ability to change line height; is that just a fact ? In which case I presume that trying to adjust using the css file is pointless if the ultimate goal is conversion to mobi format ? It is true that if I convert to azw3, the conversion does seem to match the format of the input epub. I am trying to learn something here as well as solve my problem. :-)

Thanks to all fo the help.

MOBI format is based on the outdated HTML 3 specification. It has limited formatting and does not support anything equivalent to line-height.

KF8 (azw3) format is based on a newer HTML version and does support line-height.
