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：

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}
