![真实地突出显示定理标题和编号](https://linux22.com/image/405685/%E7%9C%9F%E5%AE%9E%E5%9C%B0%E7%AA%81%E5%87%BA%E6%98%BE%E7%A4%BA%E5%AE%9A%E7%90%86%E6%A0%87%E9%A2%98%E5%92%8C%E7%BC%96%E5%8F%B7.png)
最近我遇到了这个关于 LaTeX 中酷炫文本高亮的精彩帖子以及 @Antal Spector-Zabusky 的相应回答。我确实想在我的讲义中实现这种突出显示。特别是我定义了多个环境(如定义、备注和命题)(使用mdframed
和amsthm
)。
这是一个最小的例子

\chapter{}
What the highlighting looks like:
\begin{proposition}\end{proposition}
What I want it to look like: \\
\textbf{\highlight{Satz 1.1. (my title)}}
\end{document}
这将生成如下文档:
特别要注意的是,突出显示中的“随机性”被删除了(它只是一个围绕“Satz”的透明框)。我还希望突出显示涵盖整个标题(Satz、编号、名称)。
我该如何处理这个问题?
答案1
这是一个扩展问题。您需要首先扩展参数\highlight
。这里有一种方法可以做到这一点。它定义一个变体,,\Highlight
它首先扩展参数。(当然还有其他方法,例如使用\expandafter
。)
