如何创建像这样的彩色示例环境?
答案1
下面我给出了两个选项,它们都允许分页符。
一个简单的例子
tcolorbox
(允许分页符);根据需要调整设置:代码:
\documentclass{article} \usepackage{lipsum} \usepackage[many]{tcolorbox} \definecolor{greentitle}{RGB}{61,170,61} \definecolor{greentitleback}{RGB}{216,233,213} \newtcolorbox[ auto counter, number within=section ]{myexample}[2][]{% breakable, enhanced, colback=white, colbacktitle=white, arc=0pt, leftrule=1pt, rightrule=0pt, toprule=0pt, bottomrule=0pt, titlerule=0pt, colframe=greentitleback, fonttitle=\normalcolor, overlay={ \node[ outer sep=0pt, anchor=east, text width=2.5cm, minimum height=4ex, fill=greentitleback, font=\color{greentitle}\sffamily\scshape ] at (title.west) {example~\thetcbcounter}; }, title=#2, #1 } \newcommand\Solution{\par\textbf{\textsf{Solution}}\par\medskip} \begin{document} \section{A test section} \begin{myexample}{Factorise $x^2-2x+1$} \Solution \lipsum[4] \end{myexample} \end{document}
一个简单的例子
mdframed
(允许分页符);根据需要调整设置:代码:
\documentclass{article} \usepackage{chngcntr} \usepackage[tikz]{mdframed} \usepackage{lipsum} \definecolor{greentitle}{RGB}{61,170,61} \definecolor{greentitleback}{RGB}{216,233,213} \newcounter{mdexample} \counterwithin{mdexample}{section} \newenvironment{myexample}[1] {\stepcounter{mdexample}\begin{mdframed}[ frametitle=#1, frametitlefont=\normalfont, topline=false, bottomline=false, rightline=false, linecolor=greentitleback, linewidth=2pt, singleextra={ \node[ overlay, outer sep=0pt, anchor=north east, text width=2.5cm, minimum height=4ex, fill=greentitleback, font=\color{greentitle}\sffamily\scshape ] at (O|-P) {example~\themdexample}; }, firstextra={ \node[ overlay, outer sep=0pt, anchor=north east, text width=2.5cm, minimum height=4ex, fill=greentitleback, font=\color{greentitle}\sffamily\scshape ] at (O|-P) {example~\themdexample}; } ] } {\end{mdframed}} \newcommand\Solution{\par\textbf{\textsf{Solution}}\par\medskip} \begin{document} \section{A test section} \begin{myexample}{Factorise $x^2-2x+1$} \Solution \lipsum[4] \end{myexample} \end{document}
