你可以这样做
\documentclass[border=5mm]{standalone}
\usepackage[most]{tcolorbox}
\newtcolorbox{myBox}[3][]{
arc=5mm,
lower separated=false,
fonttitle=\bfseries,
colbacktitle=green!10,
coltitle=green!50!black,
enhanced,
attach boxed title to top left={xshift=0.5cm,
yshift=-2mm},
colframe=green!50!black,
colback=green!10,
overlay={
\node[draw=green!50!black,thick,
%inner sep=2mm,
fill= green!10,rounded corners=1mm,
yshift=0pt,
xshift=-0.5cm,
left,
text=green!50!black,
anchor=east,
font=\bfseries]
at (frame.north east) {#3};},
title=#2,#1}
\begin{document}
\begin{myBox}[]{content}{Some}
content text content text content text content text content text content text content text content text content text content text content text content text content text content text content text content text content text content text content text content text content text content text content text
\end{myBox}
\end{document}
