I want to create my own beamer style for my presentations, and I follow this link to do so. I change the title page template as following
\defbeamertemplate*{title page}{texsx}[1][]
{
\begin{tikzpicture}[overlay,remember picture]
\node(title)[anchor=north, below = 0.1\textheight of current page.north] {
\begin{beamercolorbox}[center,sep=8pt,#1]{title page header}
\usebeamerfont{title}{\huge\color[rgb]{0,0,1}\inserttitle}%
\end{beamercolorbox}
};
\node(yfigure)[anchor=north, below=0.0cm of title.south] {
\usebeamercolor[fg]{titlegraphic}\inserttitlegraphic
};
\node(author)[anchor=north, below = 0.0cm of yfigure.south] {
\begin{beamercolorbox}[left,sep=8pt,#1]{author}
\usebeamerfont{author}{\small\color[rgb]{0,0.5,0.5}\insertauthor}%
\end{beamercolorbox}
};
\node(date)[anchor=north, below = 0.0cm of author.south] {
\begin{beamercolorbox}[left,sep=8pt,#1]{date}
\usebeamerfont{author}{\small\color[rgb]{0,0.5,0.5}\insertdate}%
\end{beamercolorbox}
};
\end{tikzpicture}
% % \insertinstitute
}
Which results with this output 
I find this very odd since the author anchor is north and it is set to be below of yfigure.south it should be in the middle of the page, not the left.
What am I missing?
#1is. However, I'd guess that replacingleftwithcenterwould work. – cfr Aug 23 '15 at 19:27
