The first-paragraph style:

p.first {
margin-top:0.5em;
margin-bottom: 0.0em;
text-indent:0.0em;
text-align:justify;
}

The chapter-heading style:

h2 {
margin-top:1em;
font-size: 150%;
text-indent: 0em;
font-style: italic;
text-align:center;
}


I've been told elsewhere that stripping out margin-top is standard for Kobo. (Perhaps significant: I uploaded this e-book through Draft2Digital.)

I'll look at some other Kobo samples to see if they exhibit the same behavior. Note that I'm doing this on my Windows 7 desktop, not on a Kobo reader.

Later: okay, I previewed The Girl on the Train, and it exhibits identical behavior: no margin-top, though the Look Inside sample on Amazon does show it.

Thanks!
