我有一个与这个问题相关的问题：tcolorbox 中的精确尺寸。
我产生了几种环境，“定义”、“命题”等，并且我想将我的工作统一到几种环境情况下，即制作一个通用框，适用于所有类型的环境（这里，以两种环境、定义和命题作为我的例子）。
我创建了一个环境“mybox”，尝试在其中进行这项工作。我可以使用命令将规则的颜色编码为该环境的变量，Col#2#2 可以是定义或命题，但节点\#2node（对于这些示例，必须是\propositionnode和\definitionnode）无法识别，如在编译中看到的。我该如何修复这个问题？
根据引用的原始 .tex 文件的代码项目如下：

编译后得到如下结果，我们可以看到标题节点没有出现在框中：
答案1
一个可能的解决方案是定义几个styles将在tcolorbox定义内部使用的。
这里mystyle定义了一个具有两个参数的通用框，第一个参数是颜色，第二个参数是右上角框中使用的标签。
右上角的框由\newcommand两个参数定义：标签和颜色。
标题定义了另一种样式。此定义不考虑在https://tex.stackexchange.com/a/395963/1952。
再次，就像https://tex.stackexchange.com/a/396010/1952最初提议的环境已被取代\newtcolorboxes

更新
我已将varwidth boxed node其改为tikznode boxed node。这样就可以修复minimum width以解决短标题问题。
解决了右下角线的问题，绘制了角落default，如果有标题框，则再次绘制下线直到标题结束。
