[Tex/LaTex] Customize beamer block style

beamer

I am using Montpellier theme with beamer, however the block style have no default background etc. I tried a few ways to make it look like the style of Boadilla, but I can't reproduce it good enough.

Being new to beamer, the search led me to customize it with setbeamercolor, but I am lost on how exactly specify color the way Boadilla did. Can you help?

\documentclass[c,compress]{beamer}
\usetheme{Montpellier}
\usecolortheme{beaver}
\useinnertheme[shadow]{rounded}

%\setbeamercolor{block title}{use=structure,fg=white,bg=blue!75!black}

\title{My title}

\begin{document}

\section{First Section}

\begin{frame}
    \frametitle{A Test}
    \begin{block}{definition}
        a test for block
    \end{block}
\end{frame}

\end{document}

If you check the contents of beamerthemeBoadilla.sty you will find:

\usecolortheme{rose}
\useinnertheme[shadow]{rounded}
\usecolortheme{dolphin}
\useoutertheme{infolines}

Thus, Boadilla uses the rose color theme for the inner theme and the dolphin color theme for the outer theme. In your code you have \usecolortheme{beaver}, which is also an inner theme. You can simply change beaver to rose, or if you want something similar but different to rose you can customize your colors based on the contents of beamercolorthemerose.sty.

Below there's one possible solution; the basic idea is to redefine the section in toc template in such a way that the mandatory argument of \section will now be used for the description of the section and will be placed inside a block in the ToCs; the optional argument of \section can be used for the headline (in case an outer theme with section in the headline is being used). Here's the code:

\documentclass[breaklinks]{beamer}
\usetheme{Boadilla}
\useoutertheme{miniframes}

\makeatletter
\AtBeginSection{%
  \begin{frame}
  \frametitle{Outline}
  \tableofcontents[currentsection]
  \end{frame}
}

\setbeamertemplate{section in toc}{\protect\block{Research Question~\inserttocsectionnumber}\inserttocsection\protect\endblock}

\begin{document}
\begin{frame}
\frametitle{General Outline}
\tableofcontents
\end{frame}

\section[Section one title]{This is section description 1}
\begin{frame}
Contents of section one
\end{frame}

\section[Section two title]{This is a very long section description. This is a very long section description. This is a very long section description. This is a very long section description.}
\begin{frame}
Contents of section two
\end{frame}

\section[Section three title]{This is section description 3}
\begin{frame}
Contents of section three
\end{frame}

\end{document}

and some of the resulting frames showing the two first partial ToCs with the descriptions inside a block (current section with normal code and other section shaded as requested) and the headline with the titles:

[Tex/LaTex] LaTeX Beamer Block “Sandwich Style”

With tcolorbox is easy to make a sandwich box. This one uses bicolor skin. There also exists a beamer skin which produces more 'a la beamer' boxes, but I don't know how to set a different background color for lower text part like bicolor does.

\documentclass{beamer}
\usepackage{tcolorbox}
\tcbuselibrary{skins}

\newtcolorbox{sandwich}[1]{bicolor, colframe=blue!75!black, colback=red!50!white, colbacklower=blue!75!black, collower=white,title=#1}

\begin{document}
\begin{frame}{Sandwich box with tcolorbox}

\begin{sandwich}{Testing 1-2-3}
This is a text
\tcblower
Yet another text
\end{sandwich}

\end{frame}
\end{document}
