\firstname和之间的空格\lastname设置为\makecvtitle。以下是来自moderncvstylecasual.sty：
\renewcommand*{\makecvtitle}{%
% recompute lengths (in case we are switching from letter to resume, or vice versa)
\recomputecvlengths%
% ensure footer with personal information
\makecvfooter%
% optional picture
\newbox{\makecvtitlepicturebox}%
\savebox{\makecvtitlepicturebox}{%
\ifthenelse{\isundefined{\@photo}}%
{}%
{%
\setlength\fboxrule{\@photoframewidth}%
\ifdim\@photoframewidth=0pt%
\setlength{\fboxsep}{0pt}\fi%
{\color{color1}\framebox{\includegraphics[width=\@photowidth]{\@photo}}}}}%
\usebox{\makecvtitlepicturebox}%
% name
\@initializelength{\makecvtitlepicturewidth}%
\settowidth{\makecvtitlepicturewidth}{\usebox{\makecvtitlepicturebox}}%
\parbox[b]{\textwidth-\makecvtitlepicturewidth}{%
\raggedleft\namefont{\color{color2!50}\@firstname} {\color{color2}\@lastname}}\\[-.35em]% alternate design: \MakeLowercase and no space
{\color{color2!50}\rule{\textwidth}{.25ex}}%
% optional title
\ifthenelse{\equal{\@title}{}}{}{\\[1.25em]\null\hfill\titlestyle{\@title}}\\[2.5em]% \null is required as there is no box on the line after \\, so glue (and leaders) disappears; this is in contrast to after \par, where the next line starts with an indent box (even after \noindent).
% optional quote
\ifthenelse{\isundefined{\@quote}}%
{}%
{{\null\hfill\begin{minipage}{\quotewidth}\centering\quotestyle{\@quote}\end{minipage}\hfill\null\\[2.5em]}}%
\par}% to avoid weird spacing bug at the first section if no blank line is left after \maketitle
感兴趣的线是
\parbox[b]{\textwidth-\makecvtitlepicturewidth}{%
\raggedleft\namefont{\color{color2!50}\@firstname} {\color{color2}\@lastname}}\\[-.35em]% alternate design: \MakeLowercase and no space
其中\@firstname设置为颜色color2!50（ 的 50% color2），\@lastname设置为颜色color2（ 的全部“强度” color2）。请注意两者之间的空间。这是一个常规的单词间空间；这是编译时的视觉效果template.tex风格如下casual：
调整间距的最简单方法是将任何调整包含在\firstname宏本身中：
\firstname{John\hspace{-.1em}}
\firstname如果您使用求职信作为简历的一部分，您可能需要以正确/适当的形式重新发布，否则调整也将在那里使用。
