LaTeX 样式框

Question

我需要创建这个：

我有一个包含此代码的 LaTeX 文件，但我无法使用样式来归档文本：

\newlength\sidebar
\newlength\envrule
\newlength\envborder

\addtolength{\voffset}{-0.7in}
\addtolength{\textheight}{1.5in}

\setlength\sidebar{1.5mm}
\setlength\envrule{0.4pt}
\setlength\envborder{2.5mm}

\definecolor{noteborder}{rgb}{.5,.5,.5}
\definecolor{notebg}{rgb}{.95,.95,.95}
\definecolor{exampleborder}{rgb}{.22,.22,.555}
\definecolor{examplebg}{rgb}{.9,.9,1}
\definecolor{statementborder}{rgb}{.9,0,0}
\definecolor{statementbg}{rgb}{1,.9,.9}
\definecolor{theoremborder}{rgb}{0,0,0}
\definecolor{theorembg}{rgb}{.77,.88,.66}
\definecolor{ruzova}{rgb}{1,0.8,0.8}
\definecolor{zluta}{rgb}{1,1,0.5}
\definecolor{hrasek}{rgb}{0.79,1,0.45}

\newsavebox\envbox

\definecolor{red}{rgb}{0.9, 0, 0}

你能告诉我它是怎么做到的吗？:)

您可以使用tcolorbox包裹：

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

\definecolor{mybox}{RGB}{246,51,46}

\newtcolorbox[auto counter,number within=section]{mydefi}{
  enhanced,
  breakable,
  arc=0pt,
  outer arc=0pt,
  rightrule=0pt,
  toprule=0pt,
  bottomrule=0pt,
  leftrule=3pt,
  colframe=mybox,
  colback=mybox!30,
  attach boxed title to top left,
  boxed title style={size=small,colback=red,arc=0pt,outer arc=0pt,colupper=white},
  title=Definice~\thetcbcounter,
}

\begin{document}

\begin{mydefi}
\lipsum[1]
\end{mydefi}

\end{document}
