Tweaks/conversion/layout preferences etc

AlexBell · 02-17-2011, 02:28 AM

The background:
I am most grateful to Kovid and the team for giving me the ability to convert books to ePub format so that I can read them on my Sony 650. I very much appreciate the ability to take a mobi format book and transfer to my Sony, and have calibre automatically convert it.
But almost all the mobi to ePub ebook conversions I have done have no paragraph indent and no space between paragraphs, and I very much prefer paragraphs to have an indent.
I have used the Tweak utility a couple of times to text-indent: 1em; to the stylesheet.css, and it seems to work. But it was hard to know where to put this; one book has a 'title' class which governed the layout of paragraphs, and the other has a 'calibre7' class which so far as I can tell did the same job - the second book does not have a 'title' class defined in the stylesheet.

The questions:
1. Do the different classes found in an ePub converted by book follow a set format so that e.g. the calibre7 class in one book has the same function as the calibre7 class in another book? If so,
2. Is there a list available of what the various classes do?
3. Alternatively, is it possible to tell calibre before it converts the ebook that it should indent paragraphs? And if so, how?

Regards, Alex

When converting a book, in conversion dialog, Look'n'Feel
Tick 'Remove spacing between paragraphs', then on right side adjust indent.
Then also Tick 'Insert blank line'.

#1: Not guaranteed to stay the same (or have the same values).
I see patterns when converting similar clean files . Example the class used for <body> is usually "calibre" or "calibre3". Basic <p> seems to be calibre2 or calibre4
There are lots of exceptions.

(If you convert from a OCR to Word file, expect many

)
rule 1: look at the code (I use Sigil)
rule 2: change to a different section of the book and repeat rule 1

Thanks to you both. I guess I'll rely on Perkin's suggestion, though I don't remember seeing that option last time I added a mobi file to the library; it just added it.
Another option for tweaking which occurs to me is to look for the class which contains text-align: justify; in its definition and add the text-intent: 1em; (and font-family: sans-serif; ) there. It's worked so far.

By the way, a little off topic, I've noticed that some of the tag definitions in calibre do not have a trailing semi-colon. Not a good practice in my opinion.

The last one before the } is optional as the } does it by default.
Missing in any other place is a sign of a broken
