# Why are my margins ignored? [closed]

Based on this code, I added a title but now I face the problem that the margins are ignored when I use book or scrbook with the twoside option.

\documentclass[a4paper,12pt,twoside]{book}

\usepackage[english]{babel}
\usepackage{blindtext}

\usepackage{multicol}
\setlength{\columnsep}{-2pt}

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

\tikzset{titregris/.style = {draw=gray, thick, fill=white, text=black, rectangle, rounded corners, right, minimum height=.7cm}}

\makeatletter
\mdfdefinestyle{exercisestyle}{%
outerlinewidth=1em,outerlinecolor=white,%
leftmargin=-1em,rightmargin=-1em,%
middlelinewidth=1.2pt,roundcorner=5pt,linecolor=gray,
backgroundcolor=black!10,
skipabove={0.2pt},
innertopmargin=\baselineskip,
needspace=3\baselineskip,
frametitlefont=\sffamily\bfseries,
singleextra={%
\node[titregris,xshift=1cm] at (P-|O) %
{~\mdf@frametitlefont{Text}\hbox{~}};
},
firstextra={%
\node[titregris,xshift=1cm] at (P-|O) %
{~\mdf@frametitlefont{Test}\hbox{~}};
},
}
\makeatother

What's going wrong here or better what does I need to do to make it working?

• leftmargin and rightmargin may be responsible. Quoting the mdframed manual: »Many books are written in twoside mode. In those cases it’s better to set the margins related to the site. Instead of the explained options leftmargin and rightmargin you can work with the options outermargin and innermargin – clemens Oct 4 '13 at 15:23
• @cgnieder outermargin seems to have no influence and innermargin (only) shifts the left column under the right one. Any other ideas? – susis strolch Oct 7 '13 at 16:47
