LaTeX Tcolorboxed Poster 中的定义函数

Question

我想创建一个\newtcbtheorem[number within=subsection]{definition}{Definition}{...}这样的：

必须手动插入“定义的标题”和“定义的说明”。

请有人帮我解决代码问题。

（PS：也许我必须创建一个新的环境，但我不知道该怎么做）

下面的代码和谢谢：

\documentclass{book}
\usepackage[a4paper,top=3cm,bottom=3cm,left=1.5cm,right=1.5cm]{geometry}

\usepackage{amsthm}

\posterbox[adjusted title=Definition chapetr.section.subsection.definition\_number (Title of the definition)] {column=1,row=1,span=1}{The height of the box must be automatically calculated by LaTeX according to the length of the text inside. It's possible to do it?}
\end{tcbposter}

Answer 1

使用 a 时，tcbposter您需要修复 a height，否则它将使用 a default。而且 atcbposter是不可破坏的。

如果您想自动固定高度，可以使用tcbraster或tcolorbox在另一个框内使用。第二种选择如以下代码所示。

\newtcbtheorem已为 定义A。Definitions第一次使用仅显示此环境，第二次使用显示将其包含在提供黄色背景的外部环境中的效果tcolobox。由于第二个示例由两个嵌套框组成，因此结果不会在页面之间中断。

\documentclass{book}
\usepackage[a4paper,top=3cm,bottom=3cm,left=1.5cm,right=1.5cm]{geometry}
\usepackage[x11names]{xcolor}
\usepackage{amsmath}
\usepackage{mathtools}
\usepackage{amsthm}
\usepackage{stix}
\usepackage[most]{tcolorbox}

\newtcolorbox{outerbox}{enhanced, sharp corners, boxrule=0pt, interior style={top color=yellow, bottom color=yellow!50!red}, notitle}
    
\newtcbtheorem[number within=subsection]{mydef}{Definition}{%
    enhanced, sharp corners=downhill, arc=3mm, 
    boxrule=1mm, colback=white, colframe=cyan, 
    title style={left color=black, right color=cyan}, fonttitle=\bfseries,
    separator sign none,
    description delimiters parenthesis
    }{def}

\begin{document}

\chapter{Tcolorboxed Posters}
\section{Definition: \LaTeX--function}

\subsection{With Poster of Tcolorbox--package}

\begin{mydef}{Title of the definition}{myfirstlabel}
The height of the box must be automatically calculated by LaTeX according to the length of the text inside. It's possible to do it?
\end{mydef}

\begin{outerbox}
\begin{mydef}{Title of the definition}{mysecondlabel}
The height of the box must be automatically calculated by LaTeX according to the length of the text inside. It's possible to do it?
\end{mydef}
\end{outerbox}

The definition~\ref{def:myfirstlabel} has no external box while the definition~\ref{def:mysecondlabel} although this one won't be breakable because they are nested boxes.
