LaTeX forum ⇒ General ⇒ How to center a title in a mdframed box? Topic is solved

[Cham]

I'm having a problem in centering a title inside this simple mdframed code :

Code: [Select all] [Expand/Collapse] [Download] ({untitled.tex}) Open in Overleaf

\RequirePackage[l2tabu,orthodox]{nag}
\documentclass[12pt,letterpaper]{article}
\usepackage{xcolor}
\usepackage{mdframed}
\mdfsetup{}
 
\begin{document}
 
Blablabla
 
\begin{mdframed}[
	frametitle={Some funky title},
	frametitlealignment=center, % <--- what's wrong here ?  \center doesn't fix this.
	frametitlefont=\sffamily,
	frametitlerule=true,
	frametitlebackgroundcolor=gray!20,
	linecolor=black,
	backgroundcolor=white,
	linewidth=0.5pt,
	leftmargin=0cm,
	rightmargin=0cm,
	topline=true,
	bottomline=true,
	innertopmargin=1ex,
	shadow=true,
	shadowsize=1.5pt,
	shadowcolor=gray!30
]
 
Some braindead blabla in a cool box.
 
\end{mdframed}
 
\end{document}

The mdframed package documentation doesn't give the options to be used for the frametitlealignment command, except default=\raggedleft.

nag gives an error message about the centering command.

What should be the proper solution to center the title ?

Why not using tcolorbox?

[Cham]

You mean replacing mdframed with tcolorbox ? mdframed is working very well, there's just this title centering which causes a nag problem. Is this a bug ?

[Johannes_B]

No idea, probably not a big.
I'll have a look later.

tcolorbox is more powerful these days.

[Cham]

Doh!

Apparently, the proper option to center the title in mdframed isn't center, or \center, it's \centering!

Code: [Select all] [Expand/Collapse] [Download] ({untitled.tex}) Open in Overleaf

frametitlealignment=\centering,

No more nag warnings.

Why haven't I tried this before? And why it isn't shown in the documentation? Such is LaTeX, I guess.

The issue appears to be solved.

[Johannes_B]

\center is never correct use. center is an environment.

We had this before.

[Cham]

Yes, but we're talking about a package with options. Most of the options are simple words, not commands, like this :

Code: [Select all] [Expand/Collapse] [Download] ({untitled.tex}) Open in Overleaf

\begin{mdframed}[
	frametitle={Put a title in there},
	frametitlerule=true,
	linecolor=black,
	backgroundcolor=white,
	...
]
 
Blabla
 
\end{mdframed}

So for the frametitlealignment option, I was expecting a simple word like "center" or "centered", not a command.
But it's working great anyway. The issue is solved.
