Quote area including a left bar

Question

Finally, I managed to create a own quote style with that:

\usepackage[most]{tcolorbox} 
\definecolor{block-gray}{gray}{0.95}

\def\signed #1{{\leavevmode\unskip\nobreak\hfil\penalty50\hskip2em
  \hbox{}\nobreak\hfil(#1)%
  \parfillskip=0pt \finalhyphendemerits=0 \endgraf}}

\newtcolorbox{zitat}{
    colback=block-gray,
    grow to right by=-10mm,
    grow to left by=-10mm, 
    boxrule=0pt,
    boxsep=0pt,
    breakable
}

\newsavebox\mybox
\newenvironment{aquote}[1]
  {\savebox\mybox{#1}\begin{zitat}}
  {\signed{\usebox\mybox}\end{zitat}}

But i looking forward using a new style. I like to have a quote style that has a gray bar on th left site and the quote area should be angular shaped. The area should include he source like in my approach above as well.

Does anyone of you have an approach? Thank you for your help.

Answer 1

I've used the original zitat tcolorbox environment and extended it a little bit, detaching a title to the upper box, with bold font, and \large as fontsize declaration.

The vertical line can be generated with the borderline west=... option, the box is breakable,as is shown in the screenshot.

\documentclass{article}



\usepackage{blindtext}
\usepackage[most]{tcolorbox} 
\definecolor{block-gray}{gray}{0.95}


\newtcolorbox{zitat}[2][]{%
    colback=block-gray,
    grow to right by=-10mm,
    grow to left by=-10mm, 
    boxrule=0pt,
    boxsep=0pt,
    breakable,
    enhanced jigsaw,
    borderline west={4pt}{0pt}{gray},
    title={#2\par},
    colbacktitle={block-gray},
    coltitle={black},
    fonttitle={\large\bfseries},
    attach title to upper={},
    #1,
}



\begin{document}
\begin{zitat}{Minimal working document}
A document that contains the relevant documentclass, the packages, a document-environment and the code that produces the issue.

\blindtext[5] 
\end{zitat}
\end{document}

Answer 2

I realized such a box a few times ago with TikZ, and here was the (not really well designed) code used.

\documentclass[a4paper, 11pt]{article}

%% Global libraries
\usepackage[textwidth=18cm,bottom=2cm,top=2cm]{geometry}

%% Libraries for graphics and colours
\usepackage{xcolor}
\usepackage{tikz}
\usepackage[skins]{tcolorbox} 

\definecolor{mygray}{RGB}{195,195,195}

\newcommand\todoFrame[2]{\vspace{.3cm}\noindent\tikz{
\node (contentnode) [draw, color = #1!25, fill=#1!15, text=black, rectangle, outer sep = 0, rounded corners = 1mm, minimum width=\linewidth-1, text width=\linewidth, align=justify, below right] at (0,0) {\noindent #2};
\draw[fill opacity = 1, color=#1, fill=#1] (0,0) rectangle ([xshift=5]contentnode.south west);}
\par}

\newcommand\todoEnv[3]{\par\todoFrame{#1}{\noindent\hspace*{.3cm}\textbf{\textcolor{#1}{\Large{#2}}}\vspace*{.2cm}\newline\noindent\hspace*{.3cm}\begin{minipage}{\dimexpr\linewidth-.3cm\relax}#3\end{minipage}}\ignorespaces}

\begin{document}
\todoEnv{mygray}{Fragment}{A \textbf{fragment} is a piece of an activity whice enable more modular activity design. It will not be wrong if we say, a fragment is a kind of \textbf{sub-activity}.}

\end{document} 

Please note that this solution will not break at page break...

Although, as suggested in the comments, tcolorbox seems more appropriate here (if anyone want to submit a response with it, feel free to do so!).

In any case, I hope it may help you.
