Vertical alignment of blocks with and without columns

beamer add tag

Sebastian Thomas (imported from SE)

In a beamer presentation, when I work with blocks in columns, LaTeX seems to add some additional vertical space before the title of the first block. How can I avoid this behaviour?

A minimal working example:

    \documentclass[t]{beamer}
    
    \begin{document}
    
    \begin{frame}{Frame without columns}
      \begin{block}{Just a block}
      \end{block}
    \end{frame}
    
    \begin{frame}{Frame with columns}
      \begin{columns}[t, onlytextwidth]
        \begin{column}{0.45\textwidth}
          \begin{block}{A block in a columns area}
          \end{block}
        \end{column}
      \end{columns}
    \end{frame}
    
    \end{document}

Beamer add this space for non-text elements (blocks, itemize, ...) at the top of columns. To undo this, you can add a negative space: 

    \documentclass[t]{beamer}
    \usecolortheme{orchid}
    
    \begin{document}
    
    \begin{frame}{Frame without columns}
      \begin{block}{Just a block}
      x
      \end{block}
    \end{frame}
    
    \begin{frame}{Frame with columns}
      \begin{columns}[t, onlytextwidth]
        \begin{column}{0.45\textwidth}
        	\vspace*{-\baselineskip}
          \begin{block}{A block in a columns area}
          x
          \end{block}
        \end{column}
      \end{columns}
    \end{frame}
    
    \end{document}
