Beamer : la taille des blocs est-elle modulable ?
Je voudrais pouvoir moduler la hauteur des blocs dans une frame. Donner frame : donner une hauteur plus grande au premier, premier bloc et diminuer la hauteur du second bloc : comment second. Comment faire ?
Voici un ECM :
\documentclass[english,10pt]{beamer}
\usetheme{JuanLesPins}
\setbeamercovered{transparent}
% \definecolor{vertmoyen}{rgb}{0.20,0.43,0.09}

\usecolortheme[named=bleuklein]{structure}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{lmodern}
\usepackage[french]{babel}
\setbeamersize{text margin left = 2mm, % normalement c'est 1 cm
text margin right = 2mm % normalement c'est 1 cm
}

\draw (0.5,0.5) node {$NH_{3}^{+} - R - NH_{3}^{+}\, (aq) +\, 2\, HO^{-}\, (aq)$};
\draw (11,0.5) node {$NH_{2} - R - NH_{2}\, (aq) +\, 2\, H_{2}O$};
\end{tikzpicture}
\end{center}
\end{block}
\begin{block}{Example of COS 16}
\begin{center}
\begin{tikzpicture}[scale=0.8]
\begin{axis}[axis x line=bottom,axis y line = left, grid=major,

ymax=9.5,
mark size=0.2pt,

\addplot table [x=volume,y=sigma,col sep=tab] {dosage_conductimetrie_COS16_2019_02_01.txt};
\end{axis}
\end{tikzpicture}
% \caption{COS16 dosage}
\end{center}
\end{block}
\end{frame}
\end{document}
Remarque : il y a beauocup de packages car c'est un extrait d'une présentation Beamer plus grande.
