I am preparing a poster with LaTeX using beamerposter
, following the examples of the beamerposter site. In these examples, the title is themed with a background color. I would like to have the title framed in a box with a double border, each border with a different color. The following picture should explain it (zoom of the upper left corner of the poster):
In order to achieve this, I tried with a beamercolorbox
or an \fcolorbox
, but I could not create a border like above.
\setlength{\fboxrule}{4pt}
\setlength{\fboxsep}{1pt}
\fcolorbox{white}{blue}{
\colorbox{white}{
Hello test
}
}
How can I create a box with a configurable border? I say configurable because I would like to control its thickness and color.
Update I have managed to almost do this with tikz box, a minipage and another box. I think this might be a over-complicated solution. The question remains open since I am still having trouble with the border to the right, it disappears due to the width of the minipage.
\definecolor{ltsiBlue1}{rgb}{0.0,0.4,1.0}
\tikzstyle{titleouterbox} = [draw=ltsiBlue1, fill=white, line width=3pt,
rectangle, inner sep=3pt, inner ysep=3pt]
\tikzstyle{titleinnerbox} = [draw=white, fill=ltsiBlue1, line width=3pt,
text=white, rectangle, inner sep=13pt, inner ysep=13pt]
\begin{tikzpicture}
\node [titleouterbox] (box){%
\begin{minipage}{1.0\textwidth}
\begin{tikzpicture}
\node [titleinnerbox] (box){%
\begin{minipage}{1.0\textwidth}
hello test
\end{minipage}
};
\end{tikzpicture}
\end{minipage}
};
\end{tikzpicture}%
