如何合并框架（mdframed）和标题（titlesec）

Question

假设我有一个框架：

\mdfdefinestyle{aaa}{
        linecolor=black!50,
        backgroundcolor=Honeydew3!80,
        roundcorner = 6pt,
        fontcolor = black,
        shadow=true,
        shadowsize=3pt,
        shadowcolor=Honeydew3!20,
        userdefinedwidth = 0.5\columnwidth,
        outerlinewidth = 0.3}

我想将其放在标题格式，例如：

\titleformat{\section}[runin]{\Large}{\thesection}{0.2cm}{\begin{aaa}}[\end{aaa}]

这不起作用。这是我得到的结果：

你知道原因是什么吗？我该如何解决？

Answer 1

我可以提出这个建议，它依赖于pstricks。我建议使用样式wrap，因此第 1 行和第 2 行之间的内衬不会改变：

\documentclass{article}

\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage[x11names]{xcolor} 
\usepackage{mdframed, framed}
\usepackage[explicit]{titlesec}
\usepackage{bigstrut}
\usepackage{pstricks, auto-pst-pdf}
\usepackage{lipsum}

\titleformat{\section}[wrap]{\Large}{}{0cm}{\psshadowbox*[linecolor=Honeydew4, fillcolor=Honeydew3!80, shadowcolor=Honeydew3!20]{\thesection.\enspace#1\bigstrut[b]}}
\titleformat{name=\section, numberless}[wrap]{\Large}{}{0cm}{\psshadowbox*[linecolor=Honeydew4, fillcolor=Honeydew3!80, shadowcolor=Honeydew3!20]{#1\bigstrut[b]}}

\begin{document}

\section{A Test section}
\lipsum[2]

\end{document} 

或者，如果您可以不用阴影，那么只需使用以下简单方法即可获得几乎相同的结果\fcolorbox：

\titleformat{\section}[runin]{\Large}{}{0cm}{\fcolorbox{Honeydew4}{Honeydew3!80}{\thesection.\enspace#1\bigstrut[b]}}

\titleformat{name=\section, numberless}[runin]{\Large}{}{0cm}{\fcolorbox{Honeydew4}{Honeydew3!80}{#1\bigstrut[b]}}
