如果我尝试编译此示例文档
\documentclass{beamer}
\begin{document}
\begin{frame}{Test}
Test
\end{frame}
\end{document}
我htlatex temp.tex得到输出：
l.34951 --- TeX4ht warning --- \Configure{frametitle}? ---
! LaTeX Error: Missing \begin{document} in `'.
See the LaTeX manual or LaTeX Companion for explanation.
Type H <return> for immediate help.
...
l.34952 ...i \EndP \HCode{<h2 class="frametitle">}
\bgroup
?

它为默认情况下未配置的幻灯片定义了可配置的挂钩。因此您还需要使用一个myconfig.cfg文件：
\Preamble{xhtml}
\Css{section.slide {border:solid black 0.4pt;margin-bottom:1em;}}
\Configure{frame}{\ifvmode\IgnorePar\fi\EndP
\HCode{<section class="slide">}
}{\ifvmode\IgnorePar\fi\EndP\HCode{</section>}}
\Configure{frametitle}{\ifvmode\IgnorePar\fi\EndP\HCode{<h2>}}{\ifvmode\IgnorePar\fi\EndP\HCode{</h2>}\par\ShowPar}
\begin{document}
\EndPreamble
使用 进行编译（不要使用htlatex，因为它已被弃用）：
make4ht -c myconfig.cfg temp.tex
结果如下：
