在 mdframed 下方写一封信

Question

有没有办法在 mdframed-box 的正下方写一些内容？

梅威瑟：

\documentclass[a4paper]{article}
\usepackage{mdframed}
\begin{document}
\begin{mdframed}[leftmargin=5mm, rightmargin=5mm]
    Text of the full space of the mdframed. Just tried to fit the space fully.
\end{mdframed}
\end{document}

接下来我将添加带有红色字母的输出：

我想直接在那个角落添加一个字母或符号（正方形、三角形、圆形等）。有没有简单的方法可以做到这一点？

Answer 1

如果要将字母放在行末，只需使用\hfill将字母设置在行末

\documentclass{article}
\pagestyle{empty}
\usepackage{mdframed, color}
\begin{document}
\begin{mdframed}[leftmargin=5mm, rightmargin=5mm]
    Text of the full space of the mdframed. Just tried to fit the
    space fully. \hfill\textcolor{red}{S}
\end{mdframed}
\end{document}

如果您想将字母进一步向下和向右移动，请明智地使用\rlap，\raisebox如下所示：

\documentclass{article}
\pagestyle{empty}
\usepackage{mdframed, color}
\begin{document}
\begin{mdframed}[leftmargin=5mm, rightmargin=5mm]
    Text of the full space of the mdframed. Just tried to fit the
    space fully. 
    \hfill\rlap{\raisebox{-\fboxsep}[0pt][0pt]{\hspace{\fboxsep}\textcolor{red}{S}}}
\end{mdframed}
\end{document}
