[tex4ht] Fwd: Getting rid of <span class="cmr-9"> breaks in footnotes

[Michal Hoftich]

Oh, I forgot to reply to all. I am experimenting with Neomutt and I am
not comfortable here yet.

My original reply:

Hello Jürgen!

Good to hear :)

These <span> elements are inserted by HT Fonts. You can suppress them,
but it is then necessary to provide configurations that insert HTML tags
for \textit, \textbf and similar commands. Fortunately, it is possible
to do that using the "fonts" option, so you don't need to configure them
yourself. So it is necessary just to configure footnotes to ignore HT
Fonts.

Try the following .cfg file:

\Preamble{xhtml,fonts}
\Configure{footnote-text}
    {\HPage{}\HCode{<div class="footnote-text">}\par\NoFonts}
    {\ifvmode \IgnorePar\fi \EndP
     \EndNoFonts\HCode{</div>}\EndHPage{}}
\Css{.footnote-text{font-size:0.9em;}}
\begin{document}
\EndPreamble

It is a direct copy from html4.4ht, I've just added the \NoFonts and
\EndNoFonts commands, so no <span> elements will be used in the footnote
text.
