Tcolorboxes 并排显示

Question

我想将两个tcolorboxes 并排放在 beamer 文档中。我习惯tcbraster将页面分成两部分。但是，这两个tcolorboxes 一个在另一个之下，而不是并排。奇怪的是，我设法对“简介”和“意义”框执行了我想要的操作，但对附图中的“单元格”和“Demes”框却无法执行。

我究竟做错了什么？

Answer 1

您的两个并排 tcolorbox 问题可以简化为以下 MWE。第一帧包含简化的 MWE。在第二帧中，我删除了两个框之间的空白行。如果您希望框顶部对齐而不是垂直居中，您可以添加raster valign=top第三帧中所示的选项：

\documentclass{beamer}
\usepackage[size=a2,orientation=portrait,scale=1.3]{beamerposter}
\setbeamersize{text margin left=5mm,text margin right=5mm} 
\usepackage[skins,most]{tcolorbox}
\tcbuselibrary{skins,raster}
\newtcolorbox{mybox}[1]{colback=white,colframe=orange, coltext=blue, arc=3mm, title=#1}
\usepackage{lipsum}

\begin{document}

\begin{frame}[fragile=singleslide,t]\centering
\begin{tcbraster}[raster column skip=0.1\columnwidth]
\begin{mybox}{Cells}
\lipsum[1]
\end{mybox}

\begin{mybox}{Demes}
 \lipsum[4]
\end{mybox}
\end{tcbraster}
\end{frame}

\begin{frame}[fragile=singleslide,t]\centering
\begin{tcbraster}[raster column skip=0.1\columnwidth]
\begin{mybox}{Cells}
\lipsum[1]
\end{mybox}
%
\begin{mybox}{Demes}
 \lipsum[4]
\end{mybox}
\end{tcbraster}
\end{frame}

\begin{frame}[fragile=singleslide,t]\centering
\begin{tcbraster}[raster column skip=0.1\columnwidth,raster valign=top]
\begin{mybox}{Cells}
\lipsum[1]
\end{mybox}
%
\begin{mybox}{Demes}
 \lipsum[4]
\end{mybox}
\end{tcbraster}
\end{frame}
\end{document}

与对齐问题无关：但我已删除该enumitem包，因为它与文档类不兼容beamer。
