如何使用 baposter 网格？

Question

我制作了一张海报，baposter它的背景很漂亮，我想展示更多内容。有些列的文本不足以一直延伸到海报底部，所以我想将整列向下移动，在海报中间留出一些空间，这样人们就可以更清楚地看到背景。为此，我想使用网格可能会有所帮助，但我没有找到任何地方展示如何使用它。下面是它的示例：我想将第二个标题向下移动。

    \documentclass[landscape,a0paper]{baposter}
\begin{document}
\begin{poster}
{grid=true,
headerborder=closed, % Adds a border around the header of content boxes
colspacing=1em, % Column spacing
background=none, % Background color for the gradient on the right side of the poster
borderColor=black, % Border color
headerColorOne=black, % Background color for the header in the content boxes (left side)
headerColorTwo=black, % Background color for the header in the content boxes (right side)
headerFontColor=white, % Text color for the header text in the content boxes
boxColorOne=white, % Background color of the content boxes
textborder=rectangle, % Format of the border around content boxes, can be: none, bars, coils, triangles, rectangle, rounded, roundedsmall, roundedright or faded
eyecatcher=true, % Set to false for ignoring the left logo in the title and move the title left
headerheight=0.1\textheight, % Height of the header
headershape=rounded, % Specify the rounded corner in the content box headers, can be: rectangle, small-rounded, roundedright, roundedleft or rounded
headerfont=\Large\bf\textsc, % Large, bold and sans serif font in the headers of content boxes
%textfont={\setlength{\parindent}{1.5em}}, % Uncomment for paragraph indentation
linewidth=2pt % Width of the border lines around content boxes
}

\headerbox{Intro}{name=intro,column=0,row=0}{
bla bla bla
 }

\headerbox{end}{name=end,column=0,below=intro}{
bla bla bla}

\end{poster}
\end{document}

所以我想要的是在两个标题框之间创建一些空间，而不是写入below=intro，以留出一些空白。
