I have a environment solution
created with xparse
and tcolorbox
. I do not understand why package \usepackage{indentfirst}
does not work inside solution
.
\documentclass[12pt]{book}
\usepackage{xparse}
\usepackage{indentfirst}
\usepackage{lipsum}
\def\Solution{Solution}
\usepackage[most, breakable, many]{tcolorbox}
\NewTColorBox[auto counter,number within=section]{solution}{+O{}}{%
breakable, enhanced,colframe=gray,colback=white,coltitle=green!40!black,
fonttitle=\bfseries,
underlay={\begin{tcbclipinterior}
\draw[help lines,step=5mm,blue!20!white,shift={(interior.north west)}]
(interior.south west) grid (interior.north east);
\end{tcbclipinterior}},
title={\Solution},
label={},
attach title to upper=\quad,
after upper={\par\hfill\textcolor{green!40!black}%
{}},
lowerbox=ignored,
#1,
}
\begin{document}
\chapter{One}
\begin{solution}
\lipsum[1-35]
\end{solution}
\end{document}
