I had a big text PDF book. I used Acrobat to convert it to html. I corrected the html file with OpenOffice, structured it carefully with styles (title 1, title2, title3). I then converted this ODT file to EPUB with
calibre (yes, here we are).
This book has about 20 chapters; all are tagged with H2 headings. I wanted to change slightly the look of these H2 (add small-caps) and so I opened the css stylesheet with Sigil.
I found a bewildering number of styles to deal with my H2 heading tags. It seems as each individual H2 tag has its own individual style: P-P22, P-P44, whatever.
So my intended correction could not take place. Could somebody comment on this behaviour? Why so many styles?
