Many thanks for all the hints. Regarding the font change, I could not figure out what was causing it and modifying class="s21" to match class="s22" did not work as strange enough both classes didn't contain and font size or "bold" instructions.
What did the trick was replacing '<span class="none2"> with '<span class="none4">
Regarding the stupid page numbers a regex in Sigil (boah, mighty stuff but as a first time contact pretty heavy
)
I just replaced <b class="calibre4">\d*</b> with nothing and here we go.
Again, thnx for the support
