Generation of simple, CSS-less HTML with htlatex
You have to do two things:
you can disable generation of css and ugly elements like
<span
class="cmti-10x-x-109">Emphasized text</span>
with some command line options:
htlatex filename "xhtml,NoFonts,-css"
You will then have to provide configurations for em and textit, as they are by default dealt only by css.
This should be done with custom config file, like myfonts.cfg
\Preamble{xhtml}
\Configure{emph}{\ifvmode\ShowPar\fi\HCode{<em>}}{\HCode{</em>}}
\Configure{textbf}{\ifvmode\ShowPar\fi\HCode{<b>}}{\HCode{</b>}}
\begin{document}
\EndPreamble
Now your htlatex call will be
htlatex filename "myfonts,-css,NoFonts"
Resulting html
<body
>
<!--l. 4--><p class="noindent" >Normal text
</p><!--l. 6--><p class="indent" > <em>Emphasized text</em>
</p><!--l. 8--><p class="indent" > <b>Bold-faced text</b> </p>
</body></html>
All command line options of tex4ht are described in this article. There are also other interesting articles about configuring of this system.
For getting rid of <p class="indent">, you can put following to the config file:
\Configure{HtmlPar}
{\EndP\Tg<p>}
{\EndP\Tg<p>}
{\HCode{</p>\Hnewline}}
{\HCode{</p>\Hnewline}}
You can use
htlatex myfile.tex "html,css-in"
This will embed css into the html file.
Note that, you may need to execute the command two times because the "css-in" option uses the .css file generated in the previous call.
