# How to add vertical space between blocks in textblock?

I am using beamerposter + textpos packages to create a scientific conference poster. I have 3 textblocks serving as columns and I place blocks inside of them. I would like to add some vertical space between blocks, and I would prefer if Latex did that automatically. How do I do that? Is there a textpos option? Or do I need to change the theme? Or is it impossible to do automatically?

\documentclass{beamer} % a package for presentations
\usepackage[orientation=portrait,size=a0,scale=1.25]{beamerposter}
\usepackage[utf8]{inputenc}
\usepackage[english]{babel}
\usepackage[absolute,overlay,showboxes]{textpos}
\usepackage{lipsum}
\usetheme{Lankton}
\usepackage{graphicx}
\setlength{\TPHorizModule}{10cm}
\setlength{\TPVertModule}{10cm}
\setlength{\parskip}{1em}

\title[Conference Name]{Poster Title}

\author{John Smith\inst{1}}

\institute[University Name]{\inst{1} University Name, Country}

\begin{document}
\begin{frame}[t]

\begin{textblock}{2.4} (.3,1)

\begin{block}{Introdus}
\begin{figure}[h!]
\includegraphics{msu_logo}
\caption{A figure!}
\label{fig:fig1}
\end{figure}
\end{block}

\begin{block}{Some Text}
\lipsum[1]
\end{block}

\begin{block}{More Text}
\lipsum[2]
\end{block}

\end{textblock}

\begin{textblock}{2.4}(3.0,1)

\begin{block}{Here we go}
\lipsum[1]
\end{block}

\begin{block}{More stuff}
\lipsum[2]
\end{block}

\end{textblock}

\end{frame}
\end{document}


Here's the example on sharelatex: https://www.sharelatex.com/read/zcrfhydqprtc

EDIT: it turns out that \block is provided by beamer, not by textpos.

To add vertical space between blocks, you could for example us \addtobeamertemplate{block end}{}{\vspace*{1.5cm}}

Off-topic:

• you don't need graphicx with beamer
• floating specifier such as [h!] don't make sense in a documentclass without floating mechanism
• instead of textpos, I'd use beamer owns column mechanism
