I want to place an \fbox
inside of some \part
, \chapter
, and \section
commands. Instead, I get this message:
Use of \@chapter doesn't match its definition.
Update:
\documentclass{article}
\usepackage{xcolor}
\begin{document}
\section{\fbox{hi}}
\end{document}

Protecting your
\fbox
in a section command (since it is fragile) allows for it to be used without problem:Alternatively, the
etoolbox
package provides\robustify{<cmd>}
which can make<cmd>
non-fragile:Similar functionality is provided by
makerobust
. Also see the discussion What is the difference between Fragile and Robust commands?
