I'm trying to create a reusable style (let's call it titlerect) for a tikz node which is supposed to look something like the following figure I quickly whipped up in Inkscape:
I imagine it should be usable like
\node[titlerect, title={The title}] at (0,0) {The content};
Quite honestly, however, I don't even know where to start so there's currently no MWE I can provide. I would be grateful for any pointers on how I might go about creating such a style.
\documentclass[tikz,border=3.14mm]{standalone}
\begin{document}
\begin{tikzpicture}[titlerect/.style={draw,inner ysep=2ex,inner
xsep=1ex,minimum width={2*width("#1")},align=center,label={[anchor=center,fill=white,font=\Large\bfseries\sffamily]above:#1}}]
\node[titlerect={The title}] at (0,0) {The content\\ more content};
\end{tikzpicture}
\end{document}
You might be better off with tcolorbox, though.
# with #### as explained here.
\tikzset{titlerect/.style={draw,inner ysep=2ex,inner xsep=1ex,minimum width={2*width("#1")},align=center,label={[anchor=center,fill=white,font=\Large\bfseries\sffamily]above:#1}}} in the preamble of the document, which would make the style global.
\node[titlerect=title, green]. I also tried \node[titlerect=title, label={[text=green]}], which does not seem to work. The text inside the node is changed as desired, just not the label.
titlerect/.style 2 args={} and using it like \node[titlerect={title}{green}]. While this also requires specifying a color when a default one should be used, it's good enough for my purposes.
