Beamer Metropolis: Change width of frametitle colorbox

beamer add tag

Sr Schneider (imported from SE)

I want to modify the width of the colorbox of the frametitle. Metropolis defines the frametitle like this:

    \defbeamertemplate{frametitle}{plain}{%
    	\nointerlineskip%
    	\begin{beamercolorbox}[%
    		wd=\paperwidth,%
    		sep=0pt,%
    		leftskip=\metropolis@frametitle@padding,%
    		rightskip=\metropolis@frametitle@padding,%
    		]{frametitle}%
    		\metropolis@frametitlestrut@start%
    		\insertframetitle%
    		\nolinebreak%
    		\metropolis@frametitlestrut@end%
    	\end{beamercolorbox}%
    }

The colored background should have a width like `wd=0.25\paperwidth`. How can I achieve this?

You can change the width of the box by modifying the `wd` key. The resulting box won't be oversized anymore, so the horizontal position has also be adjusted:


```
\documentclass{beamer}

\usetheme{moloch}% modern fork of the metropolis theme

\makeatletter
\setbeamertemplate{frametitle}{%
    \nointerlineskip%
    \hskip-\beamer@leftmargin%
    \begin{beamercolorbox}[%
            wd=.25\paperwidth,%
            sep=0pt,%
            leftskip=\moloch@frametitle@padding,%
            rightskip=\moloch@frametitle@padding,%
            ]{frametitle}%
            \moloch@frametitlestrut@start%
            \insertframetitle%
            \nolinebreak%
            \moloch@frametitlestrut@end%
    \end{beamercolorbox}
}
\makeatother

\begin{document}
	
\begin{frame}
	\frametitle{test}
  
  test
\end{frame}	
	
\end{document}
```
