Regularly seen on EPUB
My Kobo Glo enjoys a line-break just before this kind of span, even if before the span there is an nnbsp-;. (narrow non breaking space)
<span class="Endnoteanchor"><a href="../Text/chap51.xhtml#ftn27" id="bodyftn27">27</a></span>
Also, if I do not wish to see a white gap in the display, I need to use to change super
in the CSS code. I only need to do this for Kobo...
