Some time ago I realised that although one can (at least in an epub reader) force a "page break" by dividing an html page into multiple divisions, each of which has the style {page-break-before: always}, the (vertical) margin-bottom of the last element in a previous page and the margin-top in the succeeding page collapse into each other using the usual HTML rules on vertical margin collapsing. The practical effect of this is that unless the last element of the previous page is exactly at the bottom of that page, the margin-top of first element of the succeeding page effectively does not appear in the succeeding page. Currently I get round this problem by starting each division which forces a page-break with: <div class="margin-top-anchor> </div> Where the css contains: div.margin-top-anchor {line-height: 100%; margin-top: 0em; margin-bottom: -1em} i.e. so that each division starts (I hope) with a zero height line which 'anchors' the margin-top of the next element onto its own page. I had to think of this myself, once I realised what the problem was, and it does feel a bit like an ugly kludge (for example the zero height line still has a non-breaking space at its start). I wonder if any one knows a better way to achieve the same end. Bob Gibbins
