如何减少 cls 文件中各部分之间的间距？

Question

\cvsection在类文件中你可以找到例如这样的环境定义：

\newenvironment{cvsection}[1]{
    \vspace*{\beforesectionheaderspace} % <=======================================
    % Set text margins to equal \tabcolsep (6pt by default)
    \begin{adjustwidth}{\sectionheadermargin}{\sectionheadermargin}
        \textsc{\textbf{#1}}
    \end{adjustwidth}
    \vspace*{\beforesectionheaderhrulespace}
    \hrule height \sectionheaderhrlueheight
    \vspace*{\aftersectionheaderspace} 
}{}

\beforesectionheaderspace以及这样的定义：

\def\beforesectionheaderspace{5pt}

对于环境cvsubsection和的定义也是如此\aftersubsectionspace。根据您的需要使用新值（我0pt为每个值选择了新值，但您也可以使用负值...）...

因此您只需要在序言中为它们定义另一个值，例如：

% \vspace*{\beforesectionheaderspace}
\def\beforesectionheaderspace{0pt} % <================================== 5pt
% \vspace*{\aftersubsectionspace}
\def\aftersubsectionspace{0pt} % <====================================== 4pt
