我想修改 CambridgeUS 主题以保持相同的颜色，但通过更改页脚的配置如下：标题/页码带有“--”而不是“/”和副标题。
对于标题页，我想删除页眉和页脚，因为只需使用简单的 \thispagestyle{empty} 即可完成。
还有两件事：我怎样才能将文档的左右边距调整得更窄一些？怎样才能不设置阴影块，但提供下图中相同的阴影块？（如果这样做很简单，请使用剑桥主题和百合色……）。非常感谢！

答案1
以下是 CambridgeUS 使用的脚线定义（来自文件beamerouterthemeinfolines.sty）：
\defbeamertemplate*{footline}{infolines theme}
{
\leavevmode%
\hbox{%
\begin{beamercolorbox}[wd=.333333\paperwidth,ht=2.25ex,dp=1ex,center]{author in head/foot}%
\usebeamerfont{author in head/foot}\insertshortauthor\expandafter\beamer@ifempty\expandafter{\beamer@shortinstitute}{}{~~(\insertshortinstitute)}
\end{beamercolorbox}%
\begin{beamercolorbox}[wd=.333333\paperwidth,ht=2.25ex,dp=1ex,center]{title in head/foot}%
\usebeamerfont{title in head/foot}\insertshorttitle
\end{beamercolorbox}%
\begin{beamercolorbox}[wd=.333333\paperwidth,ht=2.25ex,dp=1ex,right]{date in head/foot}%
\usebeamerfont{date in head/foot}\insertshortdate{}\hspace*{2em}
\insertframenumber{} / \inserttotalframenumber\hspace*{2ex}
\end{beamercolorbox}}%
\vskip0pt%
}
显然，/您要替换的就在行上\insertframenumber{} / \inserttotalframenumber\hspace*{2ex}。
至于标题页，您可以使用它\begin{frame}[plain]来获取一个空白的标题页。
以下是重新定义脚线的 MWE：
\documentclass{beamer}
\mode<presentation> {
\usetheme{CambridgeUS}
\usecolortheme{lily}
\useinnertheme{circles} % rectangles, circles, inmargin, rounded
}
\setbeamertemplate{blocks}[rounded][shadow=true]
\makeatletter
\setbeamertemplate{footline}%{infolines theme}
{
\leavevmode%
\hbox{%
\begin{beamercolorbox}[wd=.333333\paperwidth,ht=2.25ex,dp=1ex,center]{author in head/foot}%
\usebeamerfont{author in head/foot}\insertshortauthor\expandafter\beamer@ifempty\expandafter{\beamer@shortinstitute}{}{~~(\insertshortinstitute)}
\end{beamercolorbox}%
\begin{beamercolorbox}[wd=.333333\paperwidth,ht=2.25ex,dp=1ex,center]{title in head/foot}%
\usebeamerfont{title in head/foot}\insertshorttitle
\end{beamercolorbox}%
\begin{beamercolorbox}[wd=.333333\paperwidth,ht=2.25ex,dp=1ex,right]{date in head/foot}%
\usebeamerfont{date in head/foot}\insertshortdate{}\hspace*{2em}
\insertframenumber{} -- \inserttotalframenumber\hspace*{2ex}
\end{beamercolorbox}}%
\vskip0pt%
}
\makeatother
% gets rid of navigation symbols
\setbeamertemplate{navigation symbols}{}
% add figures numbering
\setbeamertemplate{caption}[numbered]
\setcounter{tocdepth}{1} % in the table of contents
\setcounter{secnumdepth}{2} % with a number
\title[SCI Communication]{Serial Communication Interface Evaluation} % The short title appears at the bottom of every slide, the full title is only on the title page
\subtitle{EE-491(a): Project in Electrical Energy Systems}
\author{Antoine Giraldi} % Your name
\institute[EPFL] % Your institution as it will appear on the bottom of every slide, may be shorthand to save space
{Power Electronics Laboratory, EPFL
% \inst{1}%
% EPFL %\\ % Your institution for the title page
% \and
% \inst{2}%
% Power Electronics Laboratory
%\bigskip
%\textit{Power Electronics Laboratory} % Your email address
}
\date{\today} % Date, can be changed to a custom date
\begin{document}
%------------------------------------------------
\begin{frame}[plain]
\titlepage % Print the title page as the first slide
\end{frame}
\section[Technical Approach]{Technical Approach}
%------------------------------------------------
\begin{frame}
\frametitle{Simulink implementation}
\end{frame}
\end{document}
结果如下：
您可以更改\setbeamertemplate{blocks}[rounded][shadow=true]块的外观并使用\setbeamersize{text margin left=0pt,text margin right=0pt}来更改文本边距。
如果您有任何疑问请告诉我！
