如何创建一个看起来像教科书中“示例”部分的颜色框？

Question

我想创建一个tcolorbox看起来像许多教科书中的“示例”部分，例如类似于所附的屏幕截图。

我从中找到了一段示例代码在线来源，它使用mdframed。但我想包含尽可能少的包，因此想知道是否有办法使用 重写tcolorbox。谢谢！

示例代码为：

\newlength{\framedinnerleftmargin}
\newlength{\framedinnertopmargin}
\newlength{\framedreversedinnerleftmargin}
\setlength{\framedinnerleftmargin}{\widthof{Theoreme 10.10.10}+2em}
\setlength{\framedreversedinnerleftmargin}{\widthof{Theoreme 10.10.10}+1em}
\setlength{\framedinnertopmargin}{1em}

% first argument: label in upper left corner,
% second argument: background color
\newenvironment{boxedtext}[2]{\begin{mdframed}[%
hidealllines=true,%
backgroundcolor=#2,%
innertopmargin=\framedinnertopmargin,%
innerleftmargin=\framedinnerleftmargin,%
innerrightmargin=1em%
]%
\tabto{-\framedreversedinnerleftmargin}\textbf{#1}\tabto*{0em}%
}% begin code
{\hskip 0pt\\\hspace*{\fill}\end{mdframed}\vspace{1em}} % end code

\newenvironment{summary}[0]{\begin{center}\begin{minipage}[c]{\summarywidth}\begin{spacing}{0.9}\footnotesize} % begin code
{\end{spacing}\end{minipage}\end{center}} % end code

\newcounter{question}

% optional! if you want it to start at zero
% with every new chapter/section/etc.
\numberwithin{question}{section}

\newenvironment{question}[0]
{\refstepcounter{question}\vspace{1em plus 1em}\begin{boxedtext}{Question \thequestion.}{blue!7}}%\setlength{\parskip}{0em}}
{\end{boxedtext}\vspace{-1em plus 1em}}

\newenvironment{question*}[0]
{\vspace{1em plus 1em}\begin{boxedtext}{Question.}{blue!7}}
{\end{boxedtext}\vspace{-1em plus 1em}}

开始吧。请参阅文档以tcolorbox了解更多自定义内容。

\documentclass{article}

\usepackage{blindtext}
\usepackage[skins]{tcolorbox}

\begin{document}

\newtcolorbox[auto counter,number within=section]{myexample}[2][]{%
    coltitle=black,
    title={{\bfseries Example~\thetcbcounter.}\quad#2},
    colback=black!5,
    colframe=black!10,
    coltext=blue,
    #1
}

\begin{myexample}[]{Example Title}
    Content. \blindtext[1]
\end{myexample}

\end{document}
