[Tex/LaTex] Distance of boxes in baposter

baposterboxesposters

I am making a poster using baposter. I couldn't figure out how to reduce the vertical distance of the boxes (and maybe allow them to have some vertical overlap). Any advice?

A sample code:

\documentclass[landscape,paperwidth=22in,paperheight=28in, fontscale=.5]{baposter}
\usepackage{times}
\usepackage{calc}
\usepackage{url}
\usepackage{graphicx}
\usepackage{amsmath}
\usepackage{amssymb}
\usepackage{relsize}
\usepackage{multirow}
\usepackage{booktabs}
\usepackage{setspace}
\linespread{1}
\usepackage{multicol}
\usepackage[T1]{fontenc}
\usepackage{ae}
\usepackage{lipsum}
\usepackage{tcolorbox}

\graphicspath{{images/}}
\renewcommand\refname{}

\newcommand{\RotUP}[1]{\begin{sideways}#1\end{sideways}}

 \setlength{\columnsep}{5pt}
 \setlength{\columnseprule}{0mm}

\newcommand{\compresslist}{%
 \setlength{\itemsep}{0pt}%
 \setlength{\parskip}{0pt}%
 \setlength{\parsep}{0pt}%
 }

\begin{document}

\begin{poster}{
 grid=false,
 colspacing=0.5em,
 headerColorOne=cyan!20!white!90!black,
 borderColor=cyan!30!white!90!black,
 textborder=faded,
 headerborder=open,
 headershape=roundedright,
 headershade=plain,
 background=none,
 bgColorOne=cyan!10!white,
 boxheaderheight=.5cm,
 headerheight=0.1\textheight}    
{Header}{}{}

\headerbox{\large Contribution:}{name=contribution,column=0,row=0,span=2}{
First box}

\headerbox{\large Introduction}{name=theory,column=0,row=0,span=2, below=contribution}{
Second box}



\end{poster}

\end{document}

Best Answer

The row placement is defined by the row= key. row takes a real number corresponding to the proportion of the \textheight (here your paper height minus the margins minus the poster header).

So row=0.1 places the box at a distance 0.1\textheight from the top of the poster area. If you use the relative placement keys like below= or align=, this will override the row= definition

In essence, you can place a box anywhere in the column, including overlapping another box (see the example where Box 4 overlaps Box3).

I added the headerfont key to the MWE. It isn't necessary to use formatting macros in the headerbox to set their format. It can be done globally, as indicated.

This is the result:
