How to create this type of example box? Thank you!

Best Answer

A possibility is the usage of tcolorbox like this:

\documentclass[11pt]{standalone}

\usepackage{tcolorbox}

\newcommand{\myexample}[2]{
    \begin{tcolorbox}[colback=black!5!white,colframe=black,title={Example: #1}]
        #2
    \end{tcolorbox}
}

\begin{document}
\myexample{test}{This is just a test}
\end{document}

To get something which looks more like the example image provided (thanks to Christian Hupfer) you could use:

\documentclass[11pt]{standalone}
\usepackage{tcolorbox}
\tcbuselibrary{skins}
\newcommand{\myexample}[2]{
    \begin{tcolorbox}[enhanced,colback=black!5!white,colframe=black,sharp corners,title={Example: #1}]
        #2
    \end{tcolorbox}
}

\begin{document}
\myexample{test}{This is just a test}
\end{document}

Which results in:

Look at the ntheorem, shadethm and thmtools packages, all of which let you define new environments in boxes with numbering.

And here's one possibility using mdframed:

\documentclass{article}
\usepackage{xcolor}
\usepackage[framemethod=tikz]{mdframed}

\definecolor{mybrown}{RGB}{128,64,0}

\mdfdefinestyle{mystyle}{%
linecolor=mybrown,outerlinewidth=1pt,%
frametitlerule=true,frametitlefont=\sffamily\bfseries\color{white},%
frametitlerulewidth=1pt,frametitlerulecolor=mybrown,%
frametitlebackgroundcolor=mybrown,
backgroundcolor=mybrown!05,
innertopmargin=\topskip,
roundcorner=5pt
}
\mdtheorem[style=mystyle]{example}{Example}

\gdef\Sepline{%
  \par\noindent\makebox[\linewidth][l]{%
  \hspace*{-\mdflength{innerleftmargin}}%
   \tikz\draw[thick,dashed,gray!60] (0,0) --%
        (\textwidth+\the\mdflength{innerleftmargin}+\the\mdflength{innerrightmargin},0);
  }\par\nobreak}


\begin{document}

\begin{example}[The Title]
The contents of the first part.
\Sepline
\noindent The contents of the second part.
\Sepline
\noindent The contents of the third part.
\Sepline
\noindent The contents of the fourth part.
\end{example}

\end{document}

Here's now a modification not using a theorem-like structure, but a simple environment with a mandatory argument to provide a title:

\documentclass{article}
\usepackage{xcolor}
\usepackage[framemethod=tikz]{mdframed}

\definecolor{mybrown}{RGB}{128,64,0}

\mdfdefinestyle{mystyle}{%
linecolor=mybrown,outerlinewidth=1pt,%
frametitlerule=true,frametitlefont=\sffamily\bfseries\color{white},%
frametitlerulewidth=1pt,frametitlerulecolor=mybrown,%
frametitlebackgroundcolor=mybrown,
backgroundcolor=mybrown!05,
innertopmargin=\topskip,
roundcorner=5pt
}
\newmdenv[style=mystyle]{exa}
\newenvironment{example}[1]
  {\begin{exa}[frametitle=#1]}
  {\end{exa}}

\gdef\Sepline{%
  \par\noindent\makebox[\linewidth][l]{%
  \hspace*{-\mdflength{innerleftmargin}}%
   \tikz\draw[thick,dashed,gray!60] (0,0) --%
        (\textwidth+\the\mdflength{innerleftmargin}+\the\mdflength{innerrightmargin},0);
  }\par\nobreak}

\begin{document}

\begin{example}{The Title}
The contents of the first part.
\Sepline
\noindent The contents of the second part.
\Sepline
\noindent The contents of the third part.
\Sepline
\noindent The contents of the fourth part.
\end{example}

\end{document}
