I am trying to make a poster with columns and subcolumns using Tikzposter. But the distance between the two subcolumns is larger than the one between the two main columns. How can I reduce the distance between the two subcolumns?
Here's my code and its output.
\documentclass[25pt, a0paper, landscape]{tikzposter}
\usepackage[utf8]{inputenc}
\usepackage{lipsum}
\title{Title}
\author{Author}
\institute{Institute}
\begin{document}
\maketitle
\begin{columns}
\column{0.60}
\block{Block 1}{\lipsum[1]}
\begin{subcolumns}
\subcolumn{0.50}
\block{Block 2}{\lipsum[2]}
\subcolumn{0.50}
\block{Block 3}{\lipsum[3]}
\end{subcolumns}
\column{0.40}
\block{Block 4}{\lipsum[4]}
\end{columns}
\end{document}
