% \subsection{\themename Inner Theme}
|
|
%
|
|
% A |beamer| inner theme dictates the style of the frame elements traditionally
|
|
% set in the ``body'' of each slide. These include:
|
|
%
|
|
% \begin{itemize}
|
|
% \item title, part, and section pages;
|
|
% \item itemize, enumerate, and description environments;
|
|
% \item block environments including theorems and proofs;
|
|
% \item figures and tables; and
|
|
% \item footnotes and plain text.
|
|
% \end{itemize}
