如何使用baposter網格？

Question

我使用它創建了一張海報baposter，它有一個美麗的背景，我想展示更多。有些欄位沒有足夠的文字一直到海報的底部，所以我想將整個欄向下移動，在海報中間留出一些空間，以便人們可以更清楚地看到背景。為此，我認為使用網格可能會有所幫助，但我還沒有找到任何地方顯示如何使用它。以下是其外觀的範例： 我想將第二個標頭移低。

    \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}

所以我想要的是在兩個標題框之間創建一些空間，而不是編寫below=intro，以留出一些空白。
