使用重叠的方式将各种定义的可破坏盒子放在可破坏盒子内

Question

这是我上一个问题的后续问题 tcolorbox：可以将可破坏的盒子放在彼此后面（重叠）吗？。

我的问题是：如何通过重叠来模拟可破坏盒子内部定义的各种可破坏盒子，使它们看起来像是彼此内部的？定义的盒子例如

\newtcolorbox{}

例如

Answer 1

按照提出的想法tcolorbox：可以将可破坏的盒子放在彼此后面（重叠）吗？本规范建议声明三种类型的框：topbox、middlebox和bottombox。

topbox必须是所需系列中的第一个，它包含并绘制outer title。在之后，您可以放置​​任意topbox数量的-es，并且该系列以将关闭错误的外部 tcolorbox 的结束。middleboxbottombox

middlebox绘制外线并放大以连接前一个topbox和后一个bottombox。当中间框未断开且放置在页面底部时，它会显示错误的行为。我不知道如何解决它。
