我开始只使用\vbox
等... 但有人告诉我这很可怕,所以我尽力使用 LaTeX 框,然而它们都强制退出垂直模式,这会导致垂直间距复杂化。无论如何,
\documentclass{article}
\begin{document}
XXXX
\noindent\parbox[t]{\linewidth}{\hrule width 10pt
\noindent
\mbox{\vrule
\hspace{8pt}\begin{minipage}{\dimexpr\linewidth-0.4pt-8pt\relax}
\vspace{4pt}
This is my list, you may want to configure it using package
enumitem for example to modify the label indent. The various
vspace allow to customize vertical spacing.
\begin{itemize}
\item A
\item B
\item C
\vspace{6pt}
\end{itemize}
\end{minipage}}
\hrule width 10pt
\vspace{\baselineskip}
}
XXXX
\end{document}
