我不知道如何在 Beamer 中设置特定 beamercolorbox 的字体大小。我有一个名为“box”的 beamercolorbox，我使用以下命令调用它：
\begin{beamercolorbox}[sep=4pt]{box}
我想设置此框中文本的字体大小。我尝试在序言中输入以下内容：
\setbeamerfont{box}{size={10}{12}}
但这没有任何效果。我遗漏了什么？
以下是 MWE：
\documentclass{beamer}
\usepackage[utf8]{inputenc}
\usecolortheme{beetle}
\setbeamercolor{box}{fg=black,bg=gray!50}
\begin{document}
\begin{frame}
\frametitle{Title of frame}
\begin{beamercolorbox}[sep=4pt]{box}
“A long quote. A long quote. A long quote. A long quote. A long quote. A long quote. A long quote. A long quote. A long quote. A long quote. A long quote. A long quote. A long quote. A long quote.

\end{beamercolorbox}
\end{frame}
\end{document}
输出如下：
我想减小 beamercolorbox 的字体大小，以便长引文能够更好地适应页面，不仅适用于这个特定的框，而且适用于所有“框”类型的框。
在此先感谢您的帮助！

如果您想用 固定字体大小{10}{12}，您必须使用选项。并在您想要的位置使用size*命令。\usebeamerfont
如果您想将此尺寸应用于所有box框，您可以按照以下代码newenvironment声明。mybox
\documentclass{beamer}
\usepackage[utf8]{inputenc}
\usecolortheme{beetle}
\setbeamercolor{box}{fg=black,bg=gray!50}
\setbeamerfont{box}{size*={10}{12}}
\newenvironment<>{mybox}[1][]%
{\begin{beamercolorbox}[#1]{box}\usebeamerfont{box}}{\end{beamercolorbox}}
\begin{document}
\begin{frame}
\frametitle{Title of frame}
\begin{mybox}[sep=4pt]
“A long quote. A long quote. A long quote. A long quote. A long quote. A long quote. A long quote. A long quote. A long quote. A long quote. A long quote. A long quote. A long quote. A long quote.

\end{mybox}
\end{frame}
\end{document}
