如何自定义侧边栏突出显示部分

Question

我正在准备一个主题如下的演示文稿：

\useoutertheme[height=0pt,width=3cm,left]{sidebar}
\usecolortheme{dove,sidebartab}

我想更改突出显示的部分/小节的字体颜色并使其变为粗体：

\documentclass{beamer}

\useoutertheme[height=0pt,width=3cm,left]{sidebar}
\usecolortheme{dove,sidebartab}

\setbeamercolor{section in sidebar}{fg=white, bg=black}
\setbeamerfont{section in sidebar}{series=\bfseries}

\begin{document}

\section{Section 1}

\section{Subsection 1.1}

\begin{frame}
    abc
\end{frame} 

\section{Subsection 1.2}

\section{Section 2}

\section{Subsection 2.1}

\section{Subsection 2.2}

\begin{frame}
    abc
\end{frame} 

\end{document}

不幸的是，\setbeamerfont{section in sidebar}{series=\bfseries}每个部分/小节都会变成粗体，而不仅仅是突出显示的部分。

Answer 1

您想修改\setbeamercolor{section in sidebar}{fg=blue, bg=red}

\documentclass{beamer}

\useoutertheme[height=0pt,width=3cm,left]{sidebar}
\usecolortheme{dove,sidebartab}

\setbeamercolor{section in sidebar}{fg=blue, bg=red}



\begin{document}

\section{test}

\begin{frame}
    abc
\end{frame} 

\section{testtest}

\begin{frame}
    abc
\end{frame} 

\end{document}

为了将字体改回非粗体，您可以执行以下操作：

\documentclass{beamer}

\useoutertheme[height=0pt,width=3cm,left]{sidebar}
\usecolortheme{dove,sidebartab}

%Colours
\setbeamercolor{section in sidebar}{fg=blue, bg=red}

% Fonts
\setbeamerfont{section in sidebar}{series=\bfseries}
\setbeamerfont{section in sidebar shaded}{series=\normalfont}

\makeatletter
\setbeamertemplate{section in sidebar shaded}
{%
  \vbox{%
    \vskip1ex%
    \beamer@sidebarformat{3pt}{section in sidebar shaded}{\usebeamerfont{section in sidebar shaded}\insertsectionhead}%
  }%
}
\makeatother

\begin{document}

\section{Section 1}

\begin{frame}
    abc
\end{frame} 


\section{Subsection 1.1}

\begin{frame}
    abc
\end{frame} 

\section{Subsection 1.2}

\section{Section 2}

\section{Subsection 2.1}

\section{Subsection 2.2}

\begin{frame}
    abc
\end{frame} 

\end{document}
