Based on this answer I tried to get a transparent tcolorbox
but I'd like to have a titlerule
I notice that when I add the line
- the upperbox is not transparent,
attach boxed title to top left
- the full box appears
titlerule style={red,arrows = {Hooks[arc=270]-Hooks[arc=270]}} ]
There must be a reason and I am certainly missing something.
MWE
\documentclass[tikz]{article}
\usepackage{xcolor}
\usepackage{pagecolor}
\pagecolor{yellow}
\usepackage[most]{tcolorbox}
\usetikzlibrary{arrows.meta}
\begin{document}
\begin{tcolorbox}[
% standard jigsaw,
enhanced,
title=Title,
coltitle = red,
% titlerule style={red,arrows = {Hooks[arc=270]-Hooks[arc=270]}} ] <= I'd like it to be transparent
% attach boxed title to top left, % <= I'd like it to be transparent
opacityframe=0,
opacityback=0,
opacitybacktitle=0,
]
This should have transparent backround. \\
Background should look yellow.
\end{tcolorbox}
\end{document}
