\section{Colored boxes}

\begin{tcolorbox}[colback=red!5!white,colframe=red!75!black]
  My box.
\end{tcolorbox}

\begin{tcolorbox}[colback=blue!5!white,colframe=blue!75!black,title=My title]
  My box with my title.
\end{tcolorbox}

\begin{tcolorbox}[colback=green!5!white,colframe=green!75!black]
  Upper part of my box.
  \tcblower
  Lower part of my box.
\end{tcolorbox}

\begin{tcolorbox}[colback=yellow!5!white,colframe=yellow!50!black,
  colbacktitle=yellow!75!black,title=My title]
  I can do this also with a title.
  \tcblower
  Lower part of my box.
\end{tcolorbox}

\begin{tcolorbox}[colback=yellow!10!white,colframe=red!75!black,lowerbox=invisible,
  savelowerto=\jobname_ex.tex]
  Now, we play hide and seek. Where is the lower part?
  \tcblower
  I'm invisible until you find me.
\end{tcolorbox}

\begin{tcolorbox}[colback=yellow!10!white,colframe=red!75!black,title=Here I am]
  \input{\jobname_ex.tex}
\end{tcolorbox}


\begin{tcolorbox}[enhanced,sharp corners=uphill,
    colback=blue!50!white,colframe=blue!25!black,coltext=yellow,
    fontupper=\Large\bfseries,arc=6mm,boxrule=2mm,boxsep=5mm,
    borderline={0.3mm}{0.3mm}{white}]
  Funny settings.
\end{tcolorbox}


\begin{tcolorbox}[enhanced,frame style image=blueshade.png,
  opacityback=0.75,opacitybacktitle=0.25,
  colback=blue!5!white,colframe=blue!75!black,
  title=My title]
  This box is filled with an external image.\par
  Title and interior are made partly transparent to show the image.
\end{tcolorbox}


\begin{tcolorbox}[enhanced,attach boxed title to top center={yshift=-3mm,yshifttext=-1mm},
  colback=blue!5!white,colframe=blue!75!black,colbacktitle=red!80!black,
  title=My title,fonttitle=\bfseries,
  boxed title style={size=small,colframe=red!50!black} ]
  This box uses a \textit{boxed title}. The box of the title can
  be formatted independently from the main box.

\section{\LaTeX-Examples}

\begin{tcblisting}{colback=red!5!white,colframe=red!75!black}
This is a \LaTeX\ example:
\begin{equation}
\sum\limits_{i=1}^n i = \frac{n(n+1)}{2}.
\end{equation}
\end{tcblisting}


\begin{tcblisting}{colback=red!5!white,colframe=red!75!black,listing side text,
  title=Side by side,fonttitle=\bfseries}
This is a \LaTeX\ example:
\begin{equation}
\sum\limits_{i=1}^n i = \frac{n(n+1)}{2}.
\end{equation}
\end{tcblisting}

\section{Theorems}

\newtcbtheorem[auto counter,number within=section]{theo}%
  {Theorem}{fonttitle=\bfseries\upshape, fontupper=\slshape,
     arc=0mm, colback=blue!5!white,colframe=blue!75!black}{theorem}

\begin{theo}{Summation of Numbers}{summation}
  For all natural number $n$ it holds:
  \begin{equation}
  \tcbhighmath{\sum\limits_{i=1}^n i = \frac{n(n+1)}{2}.}
  \end{equation}
\end{theo}

We have given Theorem \ref{theorem:summation} on page \pageref{theorem:summation}.

\newtcbtheorem[use counter from=theo]{antheo}%
  {Theorem}{theorem style=change,oversize,enlarge top by=1mm,enlarge bottom by=1mm,
    enhanced jigsaw,interior hidden,fuzzy halo=1mm with green,
     fonttitle=\bfseries\upshape,fontupper=\slshape,
     colframe=green!75!black,coltitle=green!50!blue!75!black}{antheorem}

\begin{antheo}{Summation of Numbers}{summation}

\section{Watermarks}

\begin{tcolorbox}[enhanced,watermark graphics=Basilica_5.png,
  watermark opacity=0.3,watermark zoom=0.9,
  colback=green!5!white,colframe=green!75!black,
  fonttitle=\bfseries, title=Box with a watermark picture]
  Here, you see my nice box with a picture as a watermark.
  This picture is automatically resized to fit the dimensions
  of my box. Instead of a picture, some text could be used or
  arbitrary graphical code. See the documentation for more options.

    \begin{tcolorbox}[beamer,colframe=blue!50!black,title=Box inside box inside box]
      And now for something completely different: Boxes!\par\medskip
      \newtcbox{\mybox}[1][]{nobeforeafter,tcbox raise base,colframe=green!50!black,colback=green!10!white,
