That is the right way of making HTML from TeX sources. TeX4ht is a
highly configurable system than any other for this purpose.

.htf stands for hypertext font.  It is an ascii font table file in
which character codes are provided for a given font in ascending
order.  Each line of a htf file will have one character.  If you open
cmr.htf, you can easily understand what I meant. Eiten Gurari has
devised a poetic character substitution system with these *.htf files
while post-processing the *.dvi output with t4ht program which is also
part of TeX4ht bundle.

Although it is not difficult to create .htf fonts for garamond or
frutiger, it will be a non-trivial task for a newbie.

your document.  You may use the default cmr fonts during translation
to HTML.  After all, html can easily be controlled by a .css and using
garamond in the LaTeX sources do not provide any particular advantage
except problems as above.

If you are familiar with  gnu tools like make, makefile, things can
easily be done.  If you are in windows you can seek the help of
cygwin.  The procedure goes like this.

1. create a file namely, variable.tex, contents of which will look
like (or adjust as you might want):

-------------------- variable.tex --------------------------
\makeatletter
\@ifundefined{Status}{\gdef\Status{0}}{}
\makeatletter
\ifcase\Status %{0}
\typeout{HTML output}
\documentclass[<options>]{article} % or whatever
%%% add any other packages or commands relevant to
%%% html generation
%
\or % Status = 1
\typeout{PDF output}
\documentclass[<options]{article}
\usepackage{garamond}
\usepackage{frutiger}
%%% add any other packages or commands relevant to
%%% PDF generation
\fi

------------------- End of variable.tex -------------------------

2. Your source document will not have the preamble part, instead it will have:

\input variable.tex
\begin[document}

3. Create makefile in the following fashion:

-------------------- makefile ---------------------

## do not use any extension, just provide the basefile name

html:
htlatex $(FILE) pdf: pdflatex '\def\Status{1}\input$(FILE)'

------------------ end of makefile ----------------

Now happily execute the following commands at the prompt:

for html:

make html

for PDF

make pdf

Hope this helps, if you have any doubts or problems, please get back to me.

Happy TeXing and best regards
