开始文档之前，第一帧 Beamer 中有多个块

Question

我需要制作更多像图片这样的框。我在 Beamer 中的演示文稿的第一个框架（标题）中附上了下面的内容。我的意思是我想创建更多像这样的蓝色框，我可以在其中放置我的信息，而且我不想将它们放在同一个框架中。我将在互联网上找到一张我想要做的图片，同时我还会附上我尝试过的代码。

\documentclass{beamer}
%Information to be included in the title page:
\title{Sample title}
\author{Anonymous}
\institute{University}
\date{2021}

\begin{document}

\frame{\titlepage}

\begin{frame}
\frametitle{Sample frame title}
   This is some text in the first frame. 
   This is some text in the first frame. 
   This is some text in the first frame.
\end{frame}
\end{document}

Answer 1

以下可能更接近预期的输出？

\documentclass{beamer}
\usecolortheme{whale}

\title{Sample title}
\author{Anonymous}
\institute{University}
\date{2021}

\makeatletter
\setbeamertemplate{title page}
{
  \vbox{}
  \vfill
  \begin{centering}
    \begin{beamercolorbox}[sep=8pt,center, rounded=true, shadow=true]{title}
      \usebeamerfont{title}\inserttitle
    \end{beamercolorbox}
    \vskip1em\par
    \setbeamercolor{author}{bg=structure!90!white,fg=white}
    \begin{beamercolorbox}[sep=8pt,center, rounded=true, shadow=true]{author}
      \usebeamerfont{author}\insertauthor
    \end{beamercolorbox}
    \setbeamercolor{institute}{bg=structure!80!white,fg=white}
    \begin{beamercolorbox}[sep=8pt,center, rounded=true, shadow=true]{institute}

    \end{beamercolorbox}\vskip0.5em
  \end{centering}
