I tried the following code, but the quotation marks at the top left is not at the right place.
\documentclass{article}
\usepackage[many]{tcolorbox}
\newtcolorbox{note}[1][\linewidth]{
enhanced,
colback = white,
boxrule = -1pt,
sharp corners,
frame code = {
\draw [line width = 5pt, blue]
([xshift = 0.3cm]frame.north west) --
(frame.north east) --
(frame.south east) --
(frame.south west) --
([yshift = -0.3cm]frame.north west);
\node [scale = 5] at (frame.north west) {``};
},
width = #1
}
\begin{document}
\begin{note}[4cm]
This is a boxed frame.
\end{note}
\end{document}
Thanks for your help!
frame.north west
, but it shifts up.\raisebox{-1em}{``}
but the problem is that it is behind the white box.
