General ⇒ Box around customized example

[darkmoor]

Hi,

I new to this forum, but hope that I have put my problem in the right place?

I have made a \newtheorem as below.

Code: Select all

\newtheorem{example}{Example}[subsection]

which works as it should. But I would like to customise it a bit more. What I would like to do; is to put at box around the example and make the margins in the example smaller than the rest of the document. But how do I do this? I have tried looking around using google but without any succes.

Hi,

you could define a new environment with the help of the the framed environment provided by the framed package (documentation in the file framed.sty itself). Take a look at the following simple example:

Code: Select all

\documentclass{article}
\usepackage{framed}
\usepackage{amsthm}
\usepackage{lipsum}% just to generate some text

\newtheorem{example}{Example}[subsection]
\newenvironment{myexample}
  {\begin{framed}\begin{example}}
  {\end{example}\end{framed}}

\begin{document}

\lipsum[1]
\begin{myexample}
\lipsum[1]
\end{myexample}
\lipsum[1]

\end{document}

You could also try the \theoremindent and \newframedtheorem commands from the ntheorem package (with the framed option).
