i came across this construct recently:
each chapter uses an empty div after the chapter title, & before the 1st text line
<div class="calibre_9"></div>
where the stylesheet definition is
.calibre_9 {
display: block;
height: 10%
}
on readers, this renders as a white space spacing of 10% of the reader page ( I think)
I guess sigil's book view can't do that because it is not really rendering page views ?
so in book view I see no space at all.
is there any alternative way of coding this that would show up in book view as well as on reader screens ?
