If you have something like:
Code:
<blockquote>
<p>"Red hair, sir, in my opinion, is dangerous."</p>
<div class="attribution">P.G. Wodehouse</div>
</blockquote>
just add "page-break-before: avoid;" the the div.attribution style. (I'm afraid some readers will not always honour it, though.)
If you don't, maybe you should.
