I've noticed that when I change the font size of a list, the font size is not automatically changed for its sublists. Is there a way to change the font size for a whole list?
\documentclass{beamer}
\usetheme{Dresden}
\setbeamertemplate{footline}
{
\begin{beamercolorbox}[colsep=1.5pt]{upper separation line foot}
\end{beamercolorbox}
\begin{beamercolorbox}[ht=2.5ex,dp=1.125ex,
leftskip=.3cm,rightskip=.3cm plus1fil]{author in head/foot}
\leavevmode{\usebeamerfont{author in head/foot}\insertshortauthor}
\hfill
{\usebeamerfont{institute in head/foot}\usebeamercolor[fg]{institute in head/foot}\insertshortinstitute}
\end{beamercolorbox}
\begin{beamercolorbox}[ht=2.5ex,dp=1.125ex,
leftskip=.3cm,rightskip=.3cm plus1fil]{title in head/foot}
{\usebeamerfont{title in head/foot}\insertshorttitle} \hfill \insertframenumber,/\inserttotalframenumber
\end{beamercolorbox}
\begin{beamercolorbox}[colsep=1.5pt]{lower separation line foot}
\end{beamercolorbox}
}
\usecolortheme{beaver}
\setbeamercolor{itemize item}{fg=darkred}
\setbeamercolor{itemize subitem}{fg=red}
\setbeamercolor{enumerate item}{fg=darkred}
\setbeamercolor{block title}{fg=darkred}
\setbeamercolor{institute in head/foot}{fg=darkred}
\usepackage[italian]{babel}
\usepackage[utf8]{inputenc}
\usepackage{graphicx}
\begin{document}
\begin{frame}
\frametitle{Frame title}
{\footnotesize
\begin{itemize}
\item First item
\item Second item
\item Third item
\item Fourth item
\item Fifth item
\begin{itemize}
\item First subitem
\item Second subitem
\end{itemize}
\end{itemize}
}
\end{frame}
\end{document}
In this example, the font size of the third and fourth item would be bigger than the size of the previous list elements.
