I am trying to make an a1 academic poster in tikzposter and need to use 3 references, which I have put into a block using bibtex.
Is there a way to make the font in the block I have put references in smaller than in the other blocks? I have used size 20pt font, which I don't want to make any smaller for the content otherwise it will be hard to read but I'm running out of space and so could do with any extra I can get!
Here is the basic code I am using, I want to make the font size in the box called References smaller:
\documentclass[20pt,a1paper, landscape,colspace=0.7cm,blockverticalspace=1cm]{tikzposter}
\usepackage{graphicx}
\usepackage{amsmath}
\usepackage{multicol}
\usepackage{adjustbox}
\usepackage{capt-of}
\setlength{\columnsep}{1.5cm}
\useblockstyle{Basic}
\usecolorstyle{Sweden}
\tikzposterlatexaffectionproofoff
\title{\parbox{0.5\linewidth}{title}}
\author{author}
\institute{institution}
\begin{document}
% Introduction.
\maketitle
\begin{columns}
\column{0.7}
\block{Introduction}
{\begin{multicols}{2}
blah blah blah
\end{multicols}
}
\begin{subcolumns}
\subcolumn{0.5}
\block{test}
{test
}
\subcolumn{0.5}
\block{test}
{testtest}
\end{subcolumns}
\column{0.3}
\block{}
{\vspace{-2cm}
\begin{tikzfigure}[caption]
\includegraphics[width=0.25\textwidth]{diagram.png}
\end{tikzfigure}
}
\block{References}
{\begingroup
\renewcommand\refname{\vskip -2cm}
\bibliographystyle{abbrv}
\bibliography{references}
\endgroup
}
\end{columns}
\end{document}
\small
or\footnotesize
inside the desired block? AFAIK that should work.
