tcolorbox 可穿透页面

Question

我试图实现一个像这样的易碎的 tcolorbox：

\usepackage{geometry}
\usepackage{lipsum}
\usepackage[skins,breakable]{tcolorbox}

\newtcolorbox{cvbox}[2][]{
  blanker,
  %leftupper=4cm,
  after skip=8mm,%   enlarge distance to the next box
  title=#2,
  breakable,
  fonttitle=\sffamily\bfseries,
  coltitle=cyan,
  %fontupper=\sffamily,%
  %#1
  overlay={%
      \ifcase\tcbsegmentstate
        % 0 = Box contains only an upper part
      \or%
        % 1 = Box contains an upper and a lower part
        %\path[draw=red] (segmentation.west)--(frame.south east);
      \else%
        % 2 = Box contains only a lower part
        %\path[draw=red] (frame.north west)--(frame.south east);
      \fi%
    }
    #1

\begin{document}

Previous stuff...

\begin{tcolorbox}[breakable]
\begin{cvbox}{Esempio:} 

 long stuff...

\end{cvbox}
\end{tcolorbox}

结果如图所示

有什么方法可以让 tcolorbox（灰色矩形）从第 25 页（就在之前的内容下方）开始，然后继续下一页？

Answer 1

嗯，您提供的代码不完整，所以我必须对其进行调整才能显示breakable tcolorbox。您的代码包含一些特殊之处：

1. tcolorbox当您随后将其放置在一般环境中时，为什么要定义一个新环境tcolorbox呢？
2. 为什么要使用该blanker选项，因为它会删除环境的框架和填充颜色（除非这正是您想要的 - 那么为什么要使用环境tcolorbox）？
3. 你定义中的第二个选项有什么用cvbox？我把它改成了1因为只有title作为选项给出。

生成可破坏盒子的代码是：

\documentclass[11pt]{article}

\usepackage{geometry}
\usepackage{lipsum}
\usepackage[skins,breakable]{tcolorbox}

\newtcolorbox{cvbox}[1][]{
    enhanced,
%   blanker, % <- removed as it suppresses box color and frame
    %leftupper=4cm,
    after skip=8mm,%   enlarge distance to the next box
    title=#1,
    breakable = true,
    fonttitle=\sffamily\bfseries,
    coltitle=cyan,
    colbacktitle=gray!10,   % <- defines background color in title
    titlerule= 0pt,         % <- sets rule underneath title 
    %fontupper=\sffamily,%
    %#1
    overlay={%
        \ifcase\tcbsegmentstate
        % 0 = Box contains only an upper part
        \or%
        % 1 = Box contains an upper and a lower part
        %\path[draw=red] (segmentation.west)--(frame.south east);
        \else%
        % 2 = Box contains only a lower part
        %\path[draw=red] (frame.north west)--(frame.south east);
        \fi%
    }
    colback = gray,         % <- defines background color in box
    colframe = black!75     % <- defines color of frame
    }
    
\begin{document}
        
        \section{Previous stuff...}
        \lipsum[2-4]

        % removed the tcolorbox environment
            \begin{cvbox}[Esempio:]
                long stuff...
                \lipsum[5-8]
            \end{cvbox}

\end{document}

上述代码的运行结果：
