新环境在另一个环境中表现不同

Question

朋友们，

请看下面的代码。问题是环境在环境内部或直接在 下hlcard时表现不同。我直接从网上选择了卡环境，但不太清楚那些长的可选参数在做什么。请帮忙。cardframe

内部的行为frame是预期的行为

宏\tcbset提供选项，即特定（或）.style的集合，否则任何未“包装”在中的选项都将全局使用，并对“层”产生副作用tcolorboxtikz/pgfkeys.styletcolorbox

嵌套框reset使用默认设置和来自的全局值tcbset。

我建议使用一种outerlayer样式和一种首先innerlayer调用outerlayer然后应用其自身设置的样式。

此外，应该用而不是将它们包装在宏中environments来定义。\newtcolorbox\newenvironment

\newtcolorbox{card}[1][]{%

\newtcolorbox{hlcard}[1][]{%
