boxed title这是使用此类标注标题选项的另一种方法。

如果标题总是短于线宽，则可以使用以下代码（我还添加了一个太长的标题示例）：

\documentclass{article}
\usepackage{tcolorbox}
\tcbuselibrary{skins,breakable}

\newtcolorbox[auto counter]{tema}[1][]{
  enhanced,breakable,
  frame hidden,interior hidden,boxrule=0pt,coltitle=black,
  title={\textsc{Tema~\thetcbcounter: #1}},
  attach boxed title to top left,
  boxed title style={enhanced,boxrule=0pt,left=4mm,right=4mm,top=1mm,bottom=1mm,
    frame hidden,
    interior code={\draw[very thick,blue!50!cyan!80!black]
      ([xshift=0.6pt,yshift=0.6pt]frame.south west)--([xshift=0.6pt,yshift=-0.6pt]frame.north west)
      --([xshift=-0.6pt,yshift=-0.6pt]frame.north east)--([xshift=-0.6pt,yshift=0.6pt]frame.south east)
      --++(-0.45em,0)--++(-115:2mm)--++(125:2mm)--cycle; }},
  underlay={%
      \draw[very thick,blue!50!cyan!80!black]
      ([xshift=7pt]interior.north west) --
      ([xshift=7pt]interior.south west); }
}

\begin{document}

   \begin{tema}[Eliminacion de Gauss-Jordan]
      Tema Hola
   \end{tema}

   \begin{tema}[A short title]
      Hola
   \end{tema}

   \begin{tema}[A very very very very very very long title]
      Hola
   \end{tema}

   \begin{tema}[A really really really really really really very very very very very very long title]
      Hola
   \end{tema}

\end{document}

如果还应该支持非常长的标题，我会添加varwidth选项内部使用的包varwidth boxed title：

\documentclass{article}
\usepackage{tcolorbox}
\tcbuselibrary{skins,breakable}
\usepackage{varwidth}

\newtcolorbox[auto counter]{tema}[1][]{
  enhanced,breakable,
  frame hidden,interior hidden,boxrule=0pt,coltitle=black,
  title={\textsc{Tema~\thetcbcounter: #1}},
  attach boxed title to top left,
  varwidth boxed title*=0pt,
  boxed title style={enhanced,boxrule=0pt,left=4mm,right=4mm,top=1mm,bottom=1mm,
    frame hidden,
    interior code={\draw[very thick,blue!50!cyan!80!black]
      ([xshift=0.6pt,yshift=0.6pt]frame.south west)--([xshift=0.6pt,yshift=-0.6pt]frame.north west)
      --([xshift=-0.6pt,yshift=-0.6pt]frame.north east)--([xshift=-0.6pt,yshift=0.6pt]frame.south east)
      --++(-0.45em,0)--++(-115:2mm)--++(125:2mm)--cycle; }},
  underlay={%
      \draw[very thick,blue!50!cyan!80!black]
      ([xshift=7pt]interior.north west) --
      ([xshift=7pt]interior.south west); }
}

\begin{document}

   \begin{tema}[Eliminacion de Gauss-Jordan]
      Tema Hola
   \end{tema}

   \begin{tema}[A short title]
      Hola
   \end{tema}

   \begin{tema}[A very very very very very very long title]
      Hola
   \end{tema}

   \begin{tema}[A really really really really really really very very very very very very long title]
      Hola

在此处输入图片描述 我在里面添加了一个幻影节点，title code用作绘制蓝色标注的骨架。新代码用注释标记。
