This is a test sentence.
This is another one.
\subsection{test}
Powered by \href{http://latex-ninja.com}{the \LaTeX{} Ninja}.
\textit{makes text italic}, a similar but different effect is achieved with \emph{which highlights}. Make some \textbf{bold} statements and don't forget the ``quotes''.\newpage will cause a manual pagebreak. Now copy this sentence into your test document.
\begin{verbatim}
@Article{CiteKey,
author = {Max Mustermann and Marie Musterfrau},
title = {Important Findings on Fast Typing in \LaTeX{}},
journal = {The LaTeX Ninja Blog},
year = {2019},
volume = {1},

}
\end{verbatim}
% What a useless example. Great I can hate on people in LaTeX using comments and they'll never know.
\verb|\emph{}| is used for highlighting.
\texttt{some code} always looks cooler in a typewriter font.
\textsc{Authors} really love it when their names are set in small caps.
\emph{I just wanted to add that somestimes people have stuff \emph{so incredibly important} to say that they want multiple layers of highlighting possible.} Thank God, \textit{unlike textit}, \verb|\emph{}| is totally up for the job.
\begin{itemize}
\item used to note down some stuff using bullet points $\to$ very practical
\item additional item
\end{itemize}
\begin{enumerate}
\item note down stuff in ordered form
\item use the \verb|enumerate| environment
\end{enumerate}

\begin{mycolorbox}{myblue}{Satz von der Winkelsumme in der euklidischen Geometrie}
Liegt das Polygon in einer euklidischen Ebene, ist die Winkelsumme durch die Formel
\begin{align*}
(n \cdot 180\degree ) - 360\degree &= (n-2) \cdot 180\degree \\
\end{align*}
gegeben, wobei $n$ für die Zahl der Ecken des Polygons steht.
