Visual Cue	Narration
Slide:	Hello and welcome to the spoken tutorial on Beamer Themes and Animation
Slide: Learning Objectives	In this tutorial, we will learn to, Use Beamer themes Do text animations using Overlay
Slide 3: System Requirements	This tutorial is recorded using Windows 11 and TeXworks editor v0.6. The steps demonstrated will work in all operating systems.
Slide 4: Prerequisites	To practise this tutorial, you should be familiar with LaTeX commands. You should also know how to create a presentation using Beamer. If not, then go through the prerequisite LaTeX spoken tutorials on this website.
Slide 5: Code Files	The files used in this tutorial are available in the Code files link on this tutorial page. Please download and extract the files Make a copy and use them for practising.
Slide: Demonstration	For this demonstration, I will be using the Beamer theme Matrix. The same is available at this link:- https://hartwork.org/beamer-theme-matrix/ Open a web browser and go to this URL.
[Firefox] Show the beamer page Navigate row-wise on the left Navigate column-wise on the top Hover the mouse on any one of the theame	Theme matrix shows various themes and color theme combinations included with the Beamer class. The rows of the matrix show the list of the different Beamer themes. The columns of the matrix show the list of the different Beamer color themes. When the cursor is placed over an image, it shows the corresponding theme and color theme.
Go to Downloads folder >> Beamer-Code-Files	Go to the folder where all the Code files are downloaded on your machine.
Open beamerThemesAndAnimation.tex in TeXworks	Open the file beamerThemesAndAnimation.tex in TeXworks editor. We will see some LaTeX code written in the file.
	Let’s try to understand the code.
Highlight: \usetheme{Warsaw}	\usetheme{Warsaw} is added to the preamble to use the Warsaw theme in Beamer. Warsaw theme displays a header on the pdf slide.
Highlight: \section and \subsection	In the document, I have inserted the \section and \subsection before each frame begins.
Highlight the section and subsection names	The section and subsection names will be displayed in the header of the slide.
At the top left drop-down >> select pdfLaTeX	At the top left, in the drop-down select pdfLaTeX, if not already selected.
Click on the green arrow button	Then click on the green arrow button to compile the file. Compile the file once again to update the theme.
Point to the pdf output	On compilation, we get the pdf output with the Warsaw theme.
Highlight the header Highlight the section names	In the slide, we can see a header. It says Beamer Themes and Introduction, one below the other.
Highlight the section names in the TeXworks file.	These are the names we defined in the sections.
Point to the green right arrow in the output window	In the output window, go to the next slide using the green-coloured right arrow.
Point to the top section. Click on “Color Themes”	Look at the header portion of the pdf slide. Section name “Beamer Themes” is seen on the left banner. And the subsection name “Themes” is seen on the right banner.
Highlight the section and subsection names in the TeXworks file.	These are the names we defined in the sections and subsections.
Highlight the section or subsection names.	You can go to any slide by clicking on the section or subsection names.
Click on Color Themes	Click on Color Themes on the top right banner.
Point to the pdf output Slide: Beamer Themes Color Themes	The respective section name and subsection name of the slide you are on, get highlighted. In my case, Beamer Themes and Color Themes get highlighted.
Point to the pdf output Slide: Introduction	Let’s click on Introduction. We are directed to the Introduction slide.
Only Narration	So, this part sort of behaves like a navigation panel.
Back to beamerThemesAndAnimation.tex	Let’s go back to the code.
[TeXworks]	Beamer themes can be combined with a color theme.
[TeXworks] Type: \usecolortheme{beaver}	To do so, before the begin document command, type the code as shown.
[TeXworks] Highlight \usetheme{Warsaw} \usecolortheme{beaver}	Always put the \usecolortheme command below the \usetheme command.
Compile twice	Now compile the file twice.
Point to the pdf output	Observe the output. colortheme command changed the color used for different elements. Let’s go back to the code.
[TeXworks] Update \usetheme{Madrid} \usecolortheme{crane}	Let’s try another theme and theme color. Update the \usetheme and \usecolortheme as shown.
[TeXworks] Highlight \usetheme{Madrid} \usecolortheme{crane}	I have set the theme to Madrid and the colortheme to crane.
Compile twice	Compile the file twice.
Point to the pdf output	We can see the generated pdf output. It has the Madrid theme along with the crane colortheme.
	Next, we will see how to add Text Animation on the slides.
Slide: Overlays	Overlay is a term used by the Beamer document class to describe the layering of slides. There are a number of commands that enable us to use overlays on text.
Only narration	Let’s see important overlays one by one. Switch to the text editor.
[TeXworks] Update the code: \section{Animation} \subsection{onslide command} \begin{frame} \frametitle{Overlay: onslide} \onslide<1->{First Line of Text} \\ \onslide<2->{Second Line of Text} \\ \onslide<3->{Third Line of Text} \end{frame}	Replace the document section code as shown here.
[TeXworks] Highlight \onslide<number->	The number inside the angle brackets tells LaTeX which slides the item should appear on. hyphen is used for continuation.
Compile	On compilation, we get the output as seen here.
Point to the pdf output Slide: Animation on onslide	In the generated pdf, click on the green right arrow to go to the next page. Observe that our three lines of text are appearing one by one in a sequential order.
Back to beamerThemesAndAnimation.tex	Switch to the editor once again.
[TeXworks] Type: \setbeamercovered{transparent}	Let’s make the text transparent on an unspecified slide. Next to the line \frametitle type the code as shown here.
Compile	Compile the file.
Point to the pdf output	Observe the output. The upcoming slide texts appear as transparent text.
[TeXworks] Type: \subsection{uncover command} \begin{frame} \frametitle{Overlay: uncover} \setbeamercovered{transparent} \uncover<1> { First Line of Text} \\ \uncover<3> {Third Line of Text} \\ \uncover<2> { Second Line of Text} \\ \uncover<5> {Fifth Line of Text} \\ \uncover<4> {Fourth Line of Text} \end{frame}	In the tex file, before the \end{document} command type the code as shown here.
[TeXworks] Highlight: \uncover<1>	Observe that here we have used \uncover instead of \onslide. \uncover is with a digit present within angular brackets. This will display the text on the slide depending on the number given here. Notice that, here we have also changed the order of appearance of the text.
Compile	Compile the file
Point to the pdf output slide: Animation \uncover command	Using the navigation arrow, go to the slide Animation \uncover command. Here only one out of five line items is appearing on the slide and the rest are transparent. When you further navigate, it displays the third item instead of the second item.
[TeXworks] Highlight \uncover<3> {Third Line of Text} \\ \uncover<2> { Second Line of Text} \\	This is because in the code the third item is mentioned as the second item. And the second item is mentioned as the third item using the \uncover command.
[TeXworks] Type: \subsection{only command} \begin{frame} \frametitle{Overlay: only} \only<1>{First Line of Text} \only<2>{Second Line of Text} \only<3>{Third Line of Text} \end{frame}	In the tex file, before the \end{document} command, type the code as shown here.
[TeXworks] Highlight \only<>	The command \only works exactly like the \uncover command. The only exception is that it does not reserve any space for the hidden text.
Compile	Compile the file.
Point to the pdf output slide: Animation \only command	Go to the slide Overlay: only command. While navigating to the right, we can see only the respective item, and not the other items. Also, all the items are appearing in the same line.
	This is how we can customize LaTeX slides as per our requirement.
Only narration	With this, we have come to the end of this tutorial. Let us summarize.
