# sans serif (sub(sub(section)) title appearance [duplicate]

I want that all `\section`, `\subsection` & `\subsubsection` entries that appear in the resulting pdf file are displayed with a sans serif font. I already tried to redefine the `\section` command as follows: `\renewcommand{\section{}}{\section{\textsf{}}}`. Unfortionately, this doesn't format. The reason probably is that I don't pass the argument of `\section`. How can I define the redefinition correctly? Francky @Leyn.eu
