everybody. I need to enclosure a text block into big square brackets. Something like this (I need to replicate it, more or less): enter image description here

I've read that it could be possible with tikz but I don't know anything about that package. Even, I found a code that reproduce something similar but with braces in this post: Adding a large brace next to a body of text The code is this:

\documentclass{article}
\usepackage{lipsum}
\usepackage[many]{tcolorbox}
\usetikzlibrary{decorations.pathreplacing}

\newtcolorbox{rightbrace}{%
    enhanced jigsaw, 
    breakable, % allow page breaks
    frame hidden, % hide the default frame
    overlay={%
        \draw [
            fill=none, % fill paper
            decoration={brace,amplitude=0.5em},
            decorate,
            ultra thick,
            gray,
        ]
        % right line
        (frame.north east)--(frame.south east);
    },
    % paragraph skips obeyed within tcolorbox
    parbox=false,
}

\begin{document}

\begin{itemize}
    \item First line
          \begin{rightbrace}
            \item Second line 
            \item Third line, which is quite long and seemingly tedious in the extreme
            \item Fourth line, which isn't as long as the third 
          \end{rightbrace}
    \item Fifth line
\end{itemize}

\begin{rightbrace}
    \lipsum[1]
\end{rightbrace}
\lipsum[2]

\end{document}

How could I put the square brackets around a block of text? (Using tikz, tcolobox or whatever package then can be useful for it).

Thanks for your help.

I adapted the code to match your picture.

This is the output:

enter image description here

And the code is:

\documentclass{article}

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

\newtcolorbox{squarebrackets}[2][]{%
  empty,
  breakable,
  boxsep=0pt,boxrule=0pt,left=5mm,right=5mm,
  toptitle=3mm,bottomtitle=1mm,
  title=\colorbox{yellow}{#2},
  coltitle=black,
  fonttitle=\bfseries,
  underlay={%
    \draw[gray!50,line width=1mm]
      ([xshift=5mm,yshift=-0.5mm]frame.north west)--
      ([xshift=0.5mm,yshift=-0.5mm]frame.north west)--
      ([xshift=0.5mm,yshift=0.5mm]frame.south west)--
      ([xshift=5mm,yshift=0.5mm]frame.south west)
      ([xshift=-5mm,yshift=-0.5mm]frame.north east)--
      ([xshift=-0.5mm,yshift=-0.5mm]frame.north east)--
      ([xshift=-0.5mm,yshift=0.5mm]frame.south east)--
      ([xshift=-5mm,yshift=0.5mm]frame.south east)
      ;
  },
  % paragraph skips obeyed within tcolorbox
  parbox=false,#1
}

\begin{document}

\lipsum[1]

\begin{squarebrackets}{Corolario}
  \lipsum[2]
\end{squarebrackets}

\lipsum[3]

\end{document}

  • Thanks, Thomas. Your code worked!! Now, I have a new problem: in several "Corolarios" I have to insert an image between two paragraph and, when I make the corolario in the squarebrackets environment, the figure environment doesn't work. So, I had to put the images ( \includegraphics) in a minipage environment. So, I lost the possibility to use \caption for automatically numbering. How could I to modify this code in order to the possiblity to use the figure environment? – Fabio Aug 04 '17 at 04:12
  • @Fabio For non-floating environments, you can use \captionof from the caption package, see e.g. https://tex.stackexchange.com/questions/45073/adding-a-caption-to-a-non-float-environment – Thomas F. Sturm Aug 04 '17 at 07:29
