I am writing a beamer presentation and I want a block at the same position in each frame. This is the code:

\documentclass[notes=show,beamer]{beamer}

\usepackage{amsfonts}
\usepackage{amsmath}
\usepackage{mathpazo}
\usepackage{hyperref}
\usepackage{multimedia}
\usepackage{graphics}

\setcounter{MaxMatrixCols}{10}
\usetheme{Boadilla}


\begin{document}

\title{Models}

\maketitle


\begin{frame}


\begin{block}{Definition}
\begin{equation*}
\boldsymbol{X}=\left\{ 
\begin{array}{ccccc}
\\ 
\\ 
\\\ 
\\ 
\end{array}%
\right. 
\end{equation*}
\end{block}

\bigskip example

\end{frame}


\begin{frame}

\begin{block}{Definition}
\begin{equation*}
\boldsymbol{X}=\left\{ 
\begin{array}{ccccc}
\\ 
\\ 
\\\ 
\\ 
%
\end{array}
\right. 
\end{equation*}
\end{block}

\textsl{Types of models}

\bigskip

\begin{tabular}{ll}
\textbf{1} &  \\ 
&  \\ 
2 &  \\ 
&  \\ 
3 & 
\end{tabular}

\end{frame}

\end{document}

But with this, code the block "Definition" in the second and in the third frames has a different position. Is there a way to keep the position of the block fixed?

  • On each slide or on each frame? They are different things. You are using two frames, but it seems that you simply need one frame with two slides using overlays. – Gonzalo Medina Sep 16 '15 at 17:22
  • @GonzaloMedina On each frame. I need the block in the same position in the two frames – user84770 Sep 16 '15 at 17:25

Using the frame positioning option [t] with frames 2 and 3 will make the two frames start at the same vertical position (top). You can deliberately add some extra vertical space before the frame starts to better manage the visual appearance.

\documentclass[notes=show]{beamer}    
\usepackage{amsfonts,lmodern}
\usepackage{amsmath}
\usepackage{mathpazo}
\usepackage{hyperref}
\usepackage{multimedia}
\usepackage{graphics}

\setcounter{MaxMatrixCols}{10}
\usetheme{Boadilla}    

\begin{document}    
\title{Models}    
\maketitle    

\begin{frame}[t]
\vspace{2em}

\begin{block}{Definition}
\begin{equation*}
\boldsymbol{X}=\left\{ 
\begin{array}{ccccc}
\\ 
\\ 
\\\ 
\\ 
\end{array}%
\right. 
\end{equation*}
\end{block}

\bigskip example

\end{frame}    

\begin{frame}[t]
\vspace{2em}

\begin{block}{Definition}
\begin{equation*}
\boldsymbol{X}=\left\{ 
\begin{array}{ccccc}
\\ 
\\ 
\\\ 
\\ 
%
\end{array}
\right. 
\end{equation*}
\end{block}

\textsl{Types of models}

\begin{tabular}{ll}
\textbf{1} &  \\

2 &  \\ 
&  \\ 
3 & 
\end{tabular}    
\end{frame}

\end{document}
