如何确保两条红线的长度相同？
我正在学习使用 beamer，我想修改一些东西。如图所示，即使我使用类似的代码，两条红线的长度也不相同：
\setbeamertemplate{frametitle}{
\vskip0.3cm
\usebeamerfont*{frametitle}\insertframetitle
\vskip-1.5ex
\begin{beamercolorbox}[colsep=0.75pt, wd=\textwidth]{lower separation line head}
\end{beamercolorbox}
}
\setbeamertemplate{navigation symbols}{}% Remove navigation
\setbeamertemplate{footline}{
\begin{beamercolorbox}[colsep=0.75pt, wd=\textwidth]{upper separation line foot}
\end{beamercolorbox}
\vskip0.3cm
}
完整代码如下
\documentclass{beamer}

脚注没有正常的文本边距，但您可以手动补偿这些长度：
