Whoa. I'm slow.
Instead of
hrs for scene-breaks and page breaks, I could use
brs. Heck, the name is
right in the name of the job I'm trying to do. 
So, make
<br class="SceneBreak" /> and
<br class="PageBreak" /> and add something like this to CSS:
Code:
br.SceneBreak {
display:none;
}
br.SceneBreak:after {
content:"* * *";
text-align:center
}
br.PageBreak {
display:none;
}
br.PageBreak {
page-break-after:always;
}
If this works, it might solve your need to add a div: don't suppress the display, and you should get one line after the break, right?
Off to test!
