Why isn't my environment using mdframed working?

Question

I am trying to make a new environment using mdframed but some of the options I am trying to define are not working.

Here is the code:

\documentclass[11pt, twosided]{book}
\usepackage[T1]{fontenc}
\usepackage[framemethod]{mdframed}
\usepackage{setspace}
\usepackage{xcolor}

\mdfdefinestyle{mdfexample1}{leftmargin=1cm,rightmargin=2cm,%
innerleftmargin=1cm,innerrightmargin=1cm,roundcorner=10pt}
\newmdenv[skipabove=15pt,
skipbelow=7pt,
rightline=true,
leftline=true,
topline=true,
bottomline=true,
linecolor=green,
backgroundcolor=green!10,
innerleftmargin=15pt,
innerrightmargin=15pt,
innertopmargin=15pt,
leftmargin=2cm,
rightmargin=2cm,
linewidth=2pt,
innerbottommargin=15pt,
roundcorner=10pt]{mBox}

\newenvironment{caixa}
{\begin{mBox}\onehalfspacing\small\color{blue}\ttfamily}{\end{mBox}}
\begin{document}
\begin{caixa}
\begin{itemize}
\item Parque 1
\item Parque 2
\end{itemize}
\end{caixa}

\begin{mdframed}[style=mdfexample1]
In any right triangle, the area of the square whose side is the hypotenuse
is equal to the sum of the areas of the squares whose sides are the two
 legs.
 \end{mdframed}
 \end{document}

This is the result I am getting:

As you can see, it is not respecting several options I define, such as roundcorners, leftmargin and rightmargin. Does anyone know what is going wrong? Thank you in advance!

Answer 1

The framemethod must be specified to be tikz, not the empty framemethod key.

If working in twoside mode, the outermargin and innermargin options should be used instead of rightmargin and leftmargin.

\documentclass[11pt, twoside]{book}
\usepackage[T1]{fontenc}
\usepackage{setspace}
\usepackage{xcolor}
\usepackage[framemethod=tikz]{mdframed}
\colorlet{azul}{blue}


\makeatletter % The code checks for twoside or oneside options
\if@twoside
\mdfdefinestyle{mdfexample1}{
  innermargin=1cm,
  outermargin=2cm,%
  innerleftmargin=1cm,
  innerrightmargin=1cm,
  roundcorner=10pt}
\else
\mdfdefinestyle{mdfexample1}{
  leftmargin=1cm,
  rightmargin=2cm,%
  innerleftmargin=1cm,
  innerrightmargin=1cm,
  roundcorner=10pt}
\fi
\makeatother

\newmdenv[skipabove=15pt,
skipbelow=7pt,
rightline=true,
leftline=true,
topline=true,
bottomline=true,
linecolor=green,
backgroundcolor=green!10,
innerleftmargin=15pt,
innerrightmargin=15pt,
innertopmargin=15pt,
leftmargin=2cm,
rightmargin=2cm,
linewidth=2pt,
innerbottommargin=15pt,
roundcorner=10pt]{mBox}

\newenvironment{caixa}
{\begin{mBox}\onehalfspacing\small\color{azul}\ttfamily}{\end{mBox}}
\begin{document}
\begin{caixa}
\begin{itemize}
\item Parque 1
\item Parque 2
\end{itemize}
\end{caixa}

\begin{mdframed}[style=mdfexample1]
In any right triangle, the area of the square whose side is the hypotenuse
is equal to the sum of the areas of the squares whose sides are the two
 legs.
