在 Beamer 中使用 Tikz 制作的动画中，我想在前两列（即box11、和box12）的框周围绘制一个更大的框（因为我在最后一张幻灯片中使用了不同的方法绘制）。更大的框应该是动画，即出现在新幻灯片上。box21box22

\tikzstyle{box} = [minimum size=1.5cm, rounded corners,rectangle, fill=blue!50]
\tikzstyle{arrow} = [thick,->,>=stealth]
\begin{document}
\begin{frame}[t]
\begin{tikzpicture}[
every edge/.style = {draw, thick, -Stealth}

您可以使用背景库，以便包含其他内容的框出现在背景中。
在这里，我没有使用这个库（我把代码放在注释之间），我使用了 TikZ 的原生可能性。
