Das farbgerahmte Paket bietet zusätzlichen vertikalen Raum am Ende, wenn es sich in einer anderen Umgebung befindet

Question

Das colorframedPaket (und sein Vorgänger framed) fügt zusätzlichen vertikalen Raum innerhalb einer anderen Umgebung hinzu.

 \documentclass{article}
 \usepackage[dvipsnames]{xcolor}
 \usepackage{colorframed}
 \colorlet{shadecolor}{lightgray}

\begin{document}

This is text before quotation, but it must be longer than one line for comparison purposes.
\begin{snugshade*}
Purely fictional thinking leads to testing text inside shaded text environments.
\end{snugshade*}
This is text between quotation, but it must be longer than one line for comparison purposes.
\begin{quotation}\begin{snugshade*}
Purely fictional thinking leads to testing text inside shaded text environments.
\end{snugshade*}\end{quotation}
This is text after quotations, but it must be longer than one line for comparison purposes.

\end{document}

Gibt es eine Möglichkeit, das zu beheben?

Answer 1

colorframedIch habe mir den Code für die Umgebung angesehen snugshade*und ihn gehackt, um eine quotedsnugshade*Umgebung zu erstellen, die einen optionalen Parameter zur Steuerung der Einrückungsstärke zulässt.

\documentclass{article}
 \usepackage[dvipsnames]{xcolor}
 \usepackage{colorframed}
 \colorlet{shadecolor}{lightgray}

\makeatletter
\newenvironment{quotedsnugshade*}[1][2em]{%
  \def\FrameCommand##1{\hskip\@totalleftmargin 
  \colorframedcolorbox{shadecolor}{##1}%
      \hskip-\linewidth \hskip-\@totalleftmargin \hskip\columnwidth}%
  \MakeFramed {\advance\hsize-\width
\advance\hsize-2\dimexpr#1\relax    %%% ADDED 
\@totalleftmargin\dimexpr#1\relax   %%% ADDED
\linewidth\hsize
    \advance\labelsep\fboxsep
    \@setminipage}%
 }{\par\unskip\@minipagefalse\endMakeFramed}
\makeatother

\end{document}

Beachten Sie, dass dies nicht getestet wird, wenn der Inhalt des schattierten Elements selbst eine Liste ist.

Answer 2

Mit dem tcolorboxPaket sind farbiger Hintergrund, Seitenumbrüche und angepasste Seitenränder auf einmal möglich (der Abstand oben und unten kann bei Bedarf angepasst werden):

\documentclass{article}

\usepackage[most]{tcolorbox}
\usepackage{lipsum}

\newtcolorbox{quack}[1][]{enhanced,breakable,frame hidden,colback=lightgray,sharp corners,size=small,left skip=1cm,right skip=1cm,#1}

\begin{document}

This is text between quotation, but it must be longer than one line for comparison purposes.
\begin{quack}
Purely fictional thinking leads to testing text inside shaded text environments.
\end{quack}
This is text after quotations, but it must be longer than one line for comparison purposes.
