Thanks Michal;

The above helped with the example I posted. But when I tried it on
a little larger file (one page long with some math in it), it failed
completely. No error where generated, but half the text is missing,
and half the math did not even render.

I put the small latex file foo.tex and the .cfg file and the PDF file
in a zip file so you can try for yourself.

https://www.12000.org/tmp/080918/test_tag.zip

The command I used is

make4ht -ulm default -c ./nma_mathjax.cfg foo.tex
"htm,0,charset=utf-8" " -cunihtf -utf8"

I used your nma_mathjax.cfg (included in the zip file)

\RequirePackage{mathjax-latex-4ht}
\Preamble{xhtml}
\begin{document}
\EndPreamble

and put the mathjax-latex-4ht.sty file in my
~/texmf/tex/local/mathjax-latex-4ht.sty so it can see it.

Here is screen shot of what the output looked like in HTML in chrome

And this is screen shot showing what it should look like (in PDF)

https://www.12000.org/tmp/080918/screen_shot_pdf.png

You can see the big difference. Large block of text is missing
as well.

If I can help test mathjax for your make4ht, I'll be happy
to. I am not sure if I am using the correct command line
options there in the command, but this is what I had before.
