我该如何设置标题在 tcolorbox 中向上移动？

Question

这是 tcolorbox 手册第 182 页的源代码。很高兴认识你。Latex 新手。很荣幸能问你第一个问题。

我不知道如何修改我的标题以使其向上：

%------------------------
\newtcolorbox{mybox}[2][]{skin=enhancedlast jigsaw,interior hidden,
boxsep=0pt,top=0pt,colframe=red,coltitle=red!50!black,
fonttitle=\bfseries\sffamily,
attach boxed title to bottom center,
boxed title style={empty,boxrule=0.5mm},
varwidth boxed title=0.5\linewidth,
underlay boxed title={
\draw[white,line width=0.5mm]
([xshift=0.3mm-\tcboxedtitleheight*2,yshift=0.3mm]title.north west)
--([xshift=-0.3mm+\tcboxedtitleheight*2,yshift=0.3mm]title.north east);
\path[draw=red,top color=white,bottom color=red!50!white,line width=0.5mm]
([xshift=0.25mm-\tcboxedtitleheight*2,yshift=0.25mm]title.north west)
cos +(\tcboxedtitleheight,-\tcboxedtitleheight/2)
sin +(\tcboxedtitleheight,-\tcboxedtitleheight/2)
-- ([xshift=0.25mm,yshift=0.25mm]title.south west)
-- ([yshift=0.25mm]title.south east)
cos +(\tcboxedtitleheight,\tcboxedtitleheight/2)
sin +(\tcboxedtitleheight,\tcboxedtitleheight/2); },
title={#2},#1}
\begin{mybox}{My title}
\lipsum[2]
\end{mybox}
%------------------------

Answer 1

下次给出编译好的文档\documentclass --> \end{document}

必须改变

• enhancedlast jigsaw到enhancedlast jigsaw
• north到south
• yshift反转

代码

\documentclass[border=3mm]{standalone}
\usepackage[most]{tcolorbox}
\usepackage{varwidth}
\usepackage{lipsum}

\newtcolorbox{mybox}[2][]{skin=enhancedlast jigsaw,interior hidden,

varwidth boxed title=0.5\linewidth,
