  1. 设置attach boxed title to top left为在左上角有一个盒装标题。
  2. 标题之上的规则自定义标题框被吸引boxed title style={overlay={...}}
  3. 框架上方的规则标题下方有阴影被吸引overlay unbroken={...}
  4. 左规则绘制于borderline west=...
  5. 阴影受控制drop fuzzy shadow 在此处输入图片描述

\begin{document}

\begin{YetAnotherTheorem}{Mittelwertsatz f\"{u}r $\mathbf{n}$ Variable}
  $f\in C^{1}(D,\mathbb{R})$. Dann gibt es auf jeder Strecke
  $[x_0,x]\subset D$ einen Punkt $\xi\in[x_0,x]$, so dass gilt
    \begin{equation*}
    f(x)-f(x_0) = \operatorname{grad} f(\xi)^{\top}(x-x_0)

尝试各种选项——

 {enhanced,arc=1mm,outer arc=1mm,
  boxrule=0mm,toprule=0mm,bottomrule=0mm,left=1mm,right=1mm,leftrule=2pt,
  titlerule=0mm,toptitle=0mm,bottomtitle=0mm,top=0mm,
  colframe=blue!50!black,colback=blue!5!white,coltitle=blue!50!black,
  colbacktitle=yellow!50!white,colback=green!5!white,
  title=#1,
  fonttitle=\bfseries\sffamily\normalsize,fontupper=\normalsize\itshape,
  }

--将产生不同的结果,如下所示
