Deep Brackets Around a Text
You have, at least two options allowing page breaks inside the framed text. You can use the tcolorbox
package:
\documentclass{article}
\usepackage{tcolorbox}
\tcbuselibrary{most}
\usepackage{lipsum}
\newtcolorbox{mybox}{
freelance,
breakable,
frame code={
\draw
([xshift=2cm]frame.north west) --
(frame.north west) --
(frame.south west) --
([xshift=2cm]frame.south west);
\draw
([xshift=-2cm]frame.north east) --
(frame.north east) --
(frame.south east) --
([xshift=-2cm]frame.south east);
},
colback=white
}
\begin{document}
\lipsum[4]
\begin{mybox}
\lipsum[4]
\end{mybox}
\lipsum[4]
\end{document}
or you can use the mdframed
package:
\documentclass{article}
\usepackage[framemethod=tikz]{mdframed}
\usepackage{lipsum}
\newmdenv[
hidealllines=true,
singleextra={
\draw
([xshift=2cm]O) --
(O) --
(O|-P) --
([xshift=2cm]O|-P);
\draw
([xshift=-2cm]P) --
(P) --
(P|-O) --
([xshift=-2cm]P|-O);
},
firstextra={
\draw
(O) --
(O|-P) --
([xshift=2cm]O|-P);
\draw
([xshift=-2cm]P) --
(P) --
(P|-O);
},
middleextra={
\draw
(O) --
(O|-P);
\draw
(P) --
(P|-O);
},
secondextra={
\draw
([xshift=2cm]O) --
(O) --
(O|-P);
\draw
(P) --
(P|-O) --
([xshift=-2cm]P|-O);
},
]{mybox}
\begin{document}
\lipsum[4]
\begin{mybox}
\lipsum[4]
\end{mybox}
\lipsum[4]
\end{document}
Here I make \specbox
a macro, rather than an environment, which means that the bracketed text cannot break across a page. One uses \fboxsep
and \fboxrule
to define the bracket offset and thickness, and \bracketarm
to define the length of the bracket arm.
I use \xcolor
and stackengine
packages to essentially stack white centered rules above and below \framebox
ed text.
\documentclass{article}
\usepackage[usestackEOL]{stackengine}
\usepackage{xcolor}
\usepackage{lipsum}
\newlength\bracketarm
\newlength\fbrp
\fboxsep 2ex
\fboxrule 2pt
\bracketarm 1in
\setlength{\fbrp}{\fboxrule+1pt}
\newcommand\specbox[1]{%
{\centering\noindent\setstackgap{S}{-\fbrp+0.5pt}%
\stackon{%
\stackunder{\framebox{\parbox{\textwidth-2\fboxsep-2\fboxrule}{#1}}}%
{\color{white}\rule{\textwidth-2\bracketarm}{\fbrp}}%
}{%
\color{white}\rule{\textwidth-2\bracketarm}{\fbrp}%
}}}%
\parskip 1ex
