如何实现navigation symbols
与footline
部分对齐。这里的footline
是这么定义的。详见附件MWE-hfut.sty
L75-86
\setbeamertemplate{footline}{
\begin{beamercolorbox}[ht=1em,dp=1em,left]{}
\hspace{1em}
\insertframenumber\hspace{0.2em}/\hspace{0.2em}\inserttotalframenumber
\ifnum\thepage>1
\hspace{1em}
{\usebeamercolor[fg]{title}\insertshorttitle}
\hspace{1em}
\insertshortauthor
\fi
\end{beamercolorbox}
}
