这是我的代码,我怎样才能将字体样式更改为 Cronos
\def\sectionfont{\bf}
\newdimen\sectionwidth
\newskip\sectionskip
\newdimen\resumewidth
\resumewidth=6.5in
\sectionskip=3.5ex plus 1ex minus -.2ex % values stolen from LaTeX
\renewcommand\section{%
\@startsection{section}{1}
{\z@}%
{-3.5ex \@plus -1ex \@minus -.2ex}%
{2.3ex \@plus.2ex}%
{\normalfont\fontsize{20}{20}\bfseries}% 11pt
}
\def\newsectionwidth#1{%
\sectionwidth=#1
\textwidth=\resumewidth
\advance\textwidth-\sectionwidth
\hsize=\textwidth
\hoffset=\sectionwidth
}
