In all my books, I set justification in css as
p {text-align: justify;}
For most books, I do not embed a font, I just have:
body {font-family: serif;}

I have just noticed that in all the epubs I have on my iPad, viewing with Books (formerly iBooks), that the justification changes depending on which font I select from the GUI:

For Athelas, Georgia, San Francisco, New York, Seravek, Times New Roman:
these all now display as left-aligned.

For Charter, Iowan, Palatino: text is justified as intended.

For books with embedded fonts, justification seems to be correct.

I cannot see any user menu to change justification.

I haven't noticed this before, (I rarely read books on my iPad, just use it to test ePubs). The iPad was on iOS 12.4.1. I just checked for updates and installed 13.2, but no change in this issue.

So, is this a real bug? Or is my CSS responsible?

PS1

I found that in the system settings, Books has a "Full justification" toggle, which is turned on.
So that is even more weird, since Books is ignoring both that and the epub's CSS to make some fonts left justified.

I guess this is one of those "throw your hands up" and/or "pull out your hair" things about how Apple does things.

So, it seem Apple decides to force justification to left depending on the font size. At larger size all are left-aligned.
I would expect this to affect wider fonts first; but Times is narrower than Palatino but switches to left before Palatino does.

So, that confirms it: it's a "pull your hair out" thing.
Just grit your teeth and move on, to mix anatomic metaphors.
