I have defined a command that uses the minipage environment to format an "example" question within my document.

\newcounter{Example} \newcommand{\example}[3]{% \refstepcounter{Example} \fbox{% \begin{minipage}{\textwidth} \subsubsection{Example \theExample:\textsf{\ #1}} {\leftskip 1em \rightskip 1em #2 } \vskip 0.5em \colorbox{lightergray}{% \begin{minipage}[c]{0.98\textwidth} #3 \end{minipage}% } %end subsubsection{Example} \end{minipage} }% }

(This code creates a command \example{<title>}{<question>}{<answer>}).

To produce this:

Current output of above code

However I need this to be able to split across multiple page breaks. At the moment the following is produced at a page break:

Undesired page splitting

This is not desirable. I know this is because of the minipage environment. Is there a way that I can produce this same output whilst allowing page breaks? (Ideally I would like no border at the bottom of the first page and no top border on the new page.)

I am compiling with TeX4ht so require either common packages or standard LaTeX/TeX.

I understand a type of list environment may be useful here but I'm unsure how to apply this to this specific case.

    Use the tcolorbox package. Commented Jun 16, 2015 at 16:36
  • why the }{ % and } % forcing word spaces? Commented Jun 16, 2015 at 16:42
  • @DavidCarlisle I'm not really sure. Why do people use those? I thought it was to stop LaTeX thinking there's a line break there. Commented Jun 16, 2015 at 16:53

    @HarrySmith a linebreak is a space so ...}% has no space after the } but you have ....} % which forces a space in that position, as you have space token before the % Commented Jun 16, 2015 at 17:11

Alternative: Use tcolorbox (Gonzalo Medina was proposing it while I wrote this answer ;-)) with the breakable option. There is a huge number of options for the shape, colours etc -- it's impossible to show them all here in a small example.

\documentclass{article} \PassOptionsToPackage{svgnames}{xcolor} \usepackage[most]{tcolorbox} \usepackage{blindtext} \newtcbtheorem[auto counter]{example}{My Example}{arc=0pt, auto outer arc, breakable,left=2pt,right=2pt,colback=LightBlue,colbacktitle=LightBlue,coltitle=black,title after break={Continued from Example \thetcbcounter},titlerule=0pt}{examples} \begin{document} In \ref{examples:brontosaurs}, we will see that... \begin{example}{Theory on Brontosaurs}{brontosaurs} \blindtext[20] \end{example} \end{document}

    I've looked at the tcolorbox package but found that TeX4ht had problems compiling it. I'm trying to stick to either very common packages or standard LaTeX/TeX because I need both .pdf documents and .html files. Commented Jun 16, 2015 at 16:51
  • @HarrySmith: You did not mention tex4ht at all in your post. Well, I posted a possible solution before tex4ht was mentioned, I won't delete it Commented Jun 16, 2015 at 16:53

    @HarrySmith -- please add your TeX4ht/ .html requirement to the statement of your question. Commented Jun 16, 2015 at 16:53

    Updated. I will certainly use this package for future documents, though! Commented Jun 16, 2015 at 16:55
