[Tex/LaTex] Set the position of blocks in beamer presentations

beamerblock

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?

Best Answer

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}

[Tex/LaTex] Blocks in Beamer

Your MWE is using the default beamer theme, which doesn't define the blocks to have the colors you want. Try using a different theme, as below. Also, to get blue/green/red use block/exampleblock/alertblock, respectively.

\documentclass[pdf]{beamer}
\usetheme{Copenhagen}
\begin{document}
\begin{frame}
\frametitle{Frame title}
\begin{block}{Observation 1}
Simmons Hall is composed of metal and concrete.
\end{block}
\begin{exampleblock}{Observation 2}
Simmons Dormitory is composed of brick.
\end{exampleblock}
\begin{alertblock}{Conclusion}
Simmons Hall $\not=$ Simmons Dormitory.
\end{alertblock}
\end{frame}
\end{document}

You can also customize how things look by using \useinnertheme{} and \usecolortheme{}. See the beamer documentation for more info.

[Tex/LaTex] Beamer: Blocks at same position from top irrespective of their contents size

Add a [t] option to the columns:

\documentclass[compress]{beamer}
\usetheme{Warsaw}
\begin{document}

\begin{frame}
\frametitle{Test1}
\begin{columns}
\column{7cm}

\begin{block}
{Block1}
\begin{description}
\item [{A:}] This is
\item [{B:}] New Item
\end{description}
\end{block}

\column{4.75cm}
\begin{block}
{Block2}
\begin{description}
\item [{A:}] This is
\item [{B:}] New Item
\end{description}
\end{block}

\end{columns}
\end{frame}


\begin{frame}
\frametitle{Test2}
\begin{columns}
\column[t]{7cm}     %new code

\begin{block}
{Block3}
\begin{description}
\item [{A:}] This is
\item [{B:}] New Item
\item [{C:}] New Item
\end{description}
\end{block}

\column[t]{4.75cm}     %new code
\begin{block}
{Block4}
\begin{description}
\item [{A:}] This is
\item [{B:}] New Item
\end{description}
\end{block}

\end{columns}
\end{frame}

\end{document}

The same result could be achieved with \begin{columns}[t] for all the columns of a specific columns environment or globally with a t class option (will affect all frame content).

Less vertical space before the blocks

This is the result with the t global option:

enter image description here

If that still is too much space, you can remove a little bit more with the T options for the columns environment, which will align the the tops of the first lines instead of the baselines of the first lines (as t does). T Can't be used as a global option.

enter image description here

If that still is too much space, you need to resort to brute force and add a

\addtobeamertemplate{frame title}{}{\vspace*{-2em}}

which will remove 2em (put whatever value you need) of vertical space after the frametitle template.

Use with caution :)
