\subsection{Colors}
\begin{tframe}
    Why different colors?
\end{tframe}

\begin{frame}{Color Picks}
    \begin{itemize}
        \item Colors suitable for color-blind readers based on \href{https://www.nature.com/articles/nmeth.1618}{Wong (2011)}

\begin{frame}{Color Picks, Cont.}
    \begin{itemize}
        \item \textcolor{blue}{Blue} for
        \begin{itemize}
            \item title page
            \item frame title (bold series)
            \item itemize item markers (enumerate item markers are in black)
            \item transition frame
        \end{itemize}
        \item \textcolor{red}{Red} for
        \begin{itemize}
            \item highlighting 
            \item description item
            \item alert environment

        \item \textcolor{orange}{Orange} for the block environment
        \item \textcolor{teal}{Teal} for the example environment
    \end{itemize}
\end{frame}

\begin{frame}[fragile]
    \frametitle{Title Page}
    \begin{itemize}
        \item Title page is inspired by \href{https://blog.hamaluik.ca/posts/better-beamer-themes/}{Kenton Hamaluik}
        \item I don't like to have author and institution information on lecture slides
        \item My students know these already!
        \item But \textbf{cbflec} allows you to have them on the title page. Try!
        \item It also works fine with aspect ratio 16:9, which I prefer for my lectures (\verb!\documentclass[aspectratio=169]{beamer}!)
    \end{itemize}
\end{frame}

\begin{frame}{Descriptions}
    \begin{itemize}
        \item Description item labels are left aligned by default
        \begin{description}
            \item[Lion] King of the savanna.
            \item[Tiger] King of the jungle.
        \end{description}
    \end{itemize}
\end{frame}

\begin{frame}{Blocks}
    \begin{block}{Let's discuss...}
        Blocks are useful to pose questions for classroom discussion!
    \end{block}
\end{frame}

\subsection{Use Transition Frames Along with Subsections}
\begin{tframe}
    Subsection titles prepare students for a new part in the lecture\\[2ex]
    Reveal here one or two key points before you explain them in detail 
\end{tframe}

\begin{frame}{Transition Frame}
    \begin{itemize}
        \item Inspiration for using transition frames like the previous one comes from \href{https://paulgp.github.io/beamer_tips.pdf}{Paul Goldsmith-Pinkham}
        \item \textbf{cbflec} offers two background color options (blue in addition to GP's yellow color suggestion) (see the last slide)
    \end{itemize}
\end{frame}

\begin{frame}[fragile]
    \frametitle{Subsections and Transtion Frames}
    \begin{itemize}
        \item Subsectioning allows you to structure your presentation
        \item Use \textbf{hyperref} package to create bookmarks 
        \item Call the \verb!tframe! environment right after \verb|\subsection{subsection title}|
        \item New frame shows the subsection title automatically as above
        \item You can insert more text to tframes as follows:
        \begin{verbatim}
            \subsection{Questions}
            \begin{tframe}
                Questions go here
            \end{tframe}
        \end{verbatim}
    \end{itemize}
\end{frame}

\begin{frame}{Table Example}
    No ``Table:" or ``Figure:" label in captions by default
    \begin{table}[h]
        \centering
        \begin{threeparttable}
            \caption{Defense R\&D Spending to Total Government R\&D Spending}

\subsection{How to Use}
\begin{tframe}
\end{tframe}

\begin{frame}[fragile]
    \frametitle{How to Use \textbf{cbflec}}
    \begin{itemize}
        \item \textbf{cbflec} offers two color options for the transition frame's background color
        \item Insert \verb!\usetheme[blue]{cbflec}! for blue
        \begin{itemize}
            \item text color on tframes will be white
        \end{itemize}
        \item Or insert \verb|\usetheme[yellow]{cbflec}| for yellow
        \begin{itemize}
            \item text color on tframes will be black
        \end{itemize}
        \item \textbf{cbflec} also offers three options for itemize item markers: circle (default), square, and triangle
        \item Insert \verb!\usetheme[blue,square]{cbflec}! to get blue transition background and square item markers (the order of parameters does not matter)
        \item Place \textit{beamerthemecbflec.sty} file in the same folder as your .tex file before calling it
    \end{itemize}
