How to have bold font in mdframed environment?

Question

I did not find bold word in the manual. My tex is:

\documentclass{article}
\usepackage[framemethod=tikz]{mdframed}
\newtheorem{question}{Question}
\mdfdefinestyle{que}{
  linecolor=cyan,
  backgroundcolor=cyan!20,
}
\surroundwithmdframed[style=que]{question}
\begin{document}
\begin{question}
Lorem. % No bolding needed here so save space here, but need to fix the above
\end{question}
\end{document}

How can you have bold font in mdframed environment?

If you want the whole environment body bold adding the option font=\bfseries to the style definition should do — cgnieder, Feb 23 '14 at 19:27
And perhaps you want to take a look at the \newmdtheoremenv command as described in Section 8 of the »mdframed« manual. — Thorsten Donig, Feb 23 '14 at 19:38
So you searched for "bold" in the manual, which returned no hits, and you instantly gave up? That's not reasonable... — jub0bs, Feb 23 '14 at 21:56

If I understand your question correctly, you want to have a kind of title for your questions and that title should be bold-faced, In this case, you can define a new theorem style and use the note field (the optional argument) to get the desired result:

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

\newtheoremstyle{mystyle}
  {\topsep}%
  {\topsep}%
  {\itshape}%
  {}%
  {\bfseries}%
  {.}%
  {.5em}%
  {\thmname{#1}~\thmnumber{#2}\thmnote{. \bfseries#3}}%
\theoremstyle{mystyle}
\newtheorem{question}{Question}
\mdfdefinestyle{que}{
  linecolor=cyan,
  backgroundcolor=cyan!20,
}
\surroundwithmdframed[style=que]{question}
\begin{document}
\begin{question}[Lorem]
Text
\end{question}
\begin{question}
Text
\end{question}
\end{document}

If, on the other side you want all the contents bold-faced, you have two options:

If you are not using amsthm, simply add font=\bfseries to the mdframed specifications:

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

\newtheorem{question}{Question}
\mdfdefinestyle{que}{
  linecolor=cyan,
  font=\bfseries,
  backgroundcolor=cyan!20,
}
\surroundwithmdframed[style=que]{question}
\begin{document}
\begin{question}
Text
\end{question}
\end{document}

If you are using amsthm, you'll need to add the specification to the theorem style:

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

\newtheoremstyle{mystyle}
  {\topsep}%
  {\topsep}%
  {\bfseries\itshape}%
  {}%
  {\bfseries}%
  {.}%
  {.5em}%
  {}%
\theoremstyle{mystyle}
\newtheorem{question}{Question}
\mdfdefinestyle{que}{
  linecolor=cyan,
  backgroundcolor=cyan!20,
}
\surroundwithmdframed[style=que]{question}
\begin{document}
\begin{question}
Text
\end{question}
\end{document}

enter image description here

Notice that italics plus bold-face might not be the best choice.

Very thorough answer again - thank you! – Léo Léopold Hertz 준영 Feb 23 '14 at 22:56 — Léo Léopold Hertz 준영, Feb 23 '14 at 22:56
