# Forbid page break after the title in mdframed

I use mdframed for my theorems like this

\mdfdefinestyle{theoremstyle}{%
%inner margins
innertopmargin=\topskip,
% outter margins
skipabove= 0.1in,
skipbelow= 0.1in,
% colrs
linecolor=red!60,
middlelinewidth=2pt,%
roundcorner=5pt,
apptotikzsetting={\tikzset{mdfframetitlebackground/.append style={%
% Title
frametitlerule=true,%
frametitlerulecolor=orange!60,
frametitlerulewidth=2pt,
% Miscellaneous
nobreak=false,
}


Sometimes page break occurs right after the theorem title. How I can prevent to break the frame between title and content?

EDIT BY yori. I'm having the same problem, so here is a MWE:

\documentclass{article}

\usepackage{lipsum}
\usepackage{mdframed}
\usepackage[a4paper,margin=1.75in]{geometry}

\begin{document}
\lipsum[1-5]

\begin{mdframed}[frametitle={The title}]%
$x^2+y^2=z^2.$
\end{mdframed}

\end{document}

• Can you add a minimal, compilable example (MWE) that demonstrates the issue? – Sean Allred Sep 16 '14 at 22:32
• The issue is that when the frame start near the end of the page and page break occurs between the title and content of the frame. I want to prevent this from happening. – itun Sep 16 '14 at 23:37
• I know what the issue is, but it'll be a little hard for us to test that it works unless we have an example where it doesn't. – Sean Allred Sep 17 '14 at 3:17
• Please add a full MWE that illustrates your problem. It will be much easier for us to reproduce your situation and find out what the issue is when we see compilable code, starting with \documentclass{...} and ending with \end{document}, not just a snippet. – Aradnix Sep 17 '14 at 5:38
• @Aradnix: I just added a MWE for itun because I'm having the same problem. I also added a working but slightly unsatisfactory solution. – yori Sep 27 '14 at 11:00

One way to solve this problem is to use the needspace option:

\documentclass{article}

\usepackage{lipsum}
\usepackage{mdframed}
\usepackage[a4paper,margin=1.75in]{geometry}

\begin{document}
\lipsum[1-5]

\begin{mdframed}[needspace=6em, frametitle={The title}]%
$x^2+y^2=z^2.$
\end{mdframed}

\end{document}


This tells mdframed to place the first page break at least 6em (vertically) into the frame. It is a bit of an unsatisfactory solution though, because it does not really express the intention, and it needs manual tweaking in the case of multi-line titles.

A second approach is to emulate the title, and add a \nobreak after the title:

\documentclass{article}

\usepackage{lipsum}
\usepackage{mdframed}
\usepackage[a4paper,margin=1.75in]{geometry}

\begin{document}
\lipsum[1-5]

\begin{mdframed}
\textbf{The title} \\ \nobreak
$x^2+y^2=z^2.$
\end{mdframed}

\end{document}


This works better, but still breaks in certain cases...
