带方形/圆形边缘的集中式/侧式盒子

Question

我正在尝试精确地重现下面的框，即带有圆边的中央框和带有方边的侧面框。

我找到了一些关于彩色盒子的文章，这些盒子背面有阴影，里面有图片等等。但我只想要这种简单的格式，和图片中的完全一样。

最好的解决办法是什么？

看tcolorbox手动的对于参数的解释。

\documentclass{book}
%\usepackage{showframe}% only for testing purpose
\usepackage[most]{tcolorbox}
\tcbset{
    opacityback=0,
    enhanced jigsaw,
    opacitybacktitle=0,
    coltitle=black,
    fonttitle=\bfseries,
    titlerule=0pt,
    titlerule style=white,
    toptitle=4pt,
    bottomtitle=0pt,
    top=2pt,
    left=1mm,
    right=1mm,
    }
\newtcolorbox{mydef}{
    title=Definition,
    grow to left by=2.5mm,% sum of the values: 1mm left margin + 1mm box sep + 0.5mm box rule = 2.5mm
    grow to right by=2.5mm,
    arc=3mm
    }
\newtcolorbox{mymarpar}[1]{
    title={\centering #1},
    sharp corners,
    grow to left by=-2.5mm
    }

\usepackage{mwe}% only for testing purpose

\begin{document}
\chapter{A chapter}
\section{A section}
\blindtext% only for testing purpose
\begin{mydef}
This is my definition. Blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah.
\end{mydef}
Some text blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah

\marginpar{\begin{mymarpar}{The title of my first margin par}
Some text in my first marigin par blah blah blah    
\end{mymarpar}}

Some other text blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah

\marginpar{\begin{mymarpar}{The title of my second margin par}
Some text in my second marigin par blah blah blah 
\end{mymarpar}}

\blindtext % only for testing purpose
\end{document}

正如 Skillmon 在他的评论中所建议的那样，如果您使用，\marginnote您可以更好地控制边距中框的垂直位置。

\documentclass{book}
\usepackage{marginnote}
%\usepackage{showframe}% only for testing purpose
\usepackage[most]{tcolorbox}
\tcbset{
    opacityback=0,
    enhanced jigsaw,
    opacitybacktitle=0,
    coltitle=black,
    fonttitle=\bfseries,
    titlerule=0pt,
    titlerule style=white,
    toptitle=4pt,
    bottomtitle=0pt,
    top=2pt,
    left=1mm,
    right=1mm,
    }
\newtcolorbox{mydef}{
    title=Definition,
    grow to left by=2.5mm,% sum of the values: 1mm left margin + 1mm box sep + 0.5mm box rule = 2.5mm
    grow to right by=2.5mm,
    arc=3mm
    }
\newtcolorbox{mymarpar}[1]{
    title={\centering #1},
    sharp corners,
    grow to left by=-2.5mm
    }

\marginnote{\begin{mymarpar}{The title of my first margin par}
Some text in my first marigin par blah blah blah

Some other text blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah

\marginnote{\begin{mymarpar}{The title of my second margin par}

\end{mymarpar}}[14pt]

\blindtext % only for testing purpose
