Time	Narration
00:01	Hello and welcome to the spoken tutorial on Beamer Themes and Animation
00:08	In this tutorial, we will learn to, Use Beamer themes
00:12	Do text animations using Overlay
00:16	This tutorial is recorded using Windows 11 and TeXworks editor v0.6.
00:26	The steps demonstrated will work in all operating systems.
00:31	To practise this tutorial, you should be familiar with LaTeX commands.
00:37	You should also know how to create a presentation using Beamer.
00:42	If not, then go through the prerequisite LaTeX spoken tutorials on this website.
00:49	The files used in this tutorial are available in the Code files link on this tutorial page.
00:56	Please download and extract the files
01:00	Make a copy and use them for practising.
01:05	For this demonstration, I will be using the Beamer theme Matrix.
01:11	The same is available at this link:- https://hartwork.org/beamer-theme-matrix/
01:14	Open a web browser and go to this URL.
01:18	Theme matrix shows various themes and color theme combinations included with the Beamer class.
01:26	The rows of the matrix show the list of the different Beamer themes.
01:32	The columns of the matrix show the list of the different Beamer color themes.
01:39	When the cursor is placed over an image, it shows the corresponding theme and color theme.
01:46	Go to the folder where all the Code files are downloaded on your machine.
01:52	Open the file beamerThemesAndAnimation.tex in TeXworks editor.
01:59	We will see some LaTeX code written in the file.
02:03	Let’s try to understand the code.
02:08	\usetheme{Warsaw} is added to the preamble to use the Warsaw theme in Beamer.
02:16	Warsaw theme displays a header on the pdf slide.
02:22	In the document, I have inserted the \section and \subsection before each frame begins.
02:30	The section and subsection names will be displayed in the header of the slide.
02:36	At the top left, in the drop-down select pdfLaTeX, if not already selected.
02:43	Then click on the green arrow button to compile the file.
02:49	Compile the file once again to update the theme.
02:53	On compilation, we get the pdf output with the Warsaw theme.
03:00	In the slide, we can see a header.
03:04	It says Beamer Themes and Introduction, one below the other.
03:10	These are the names we defined in the sections.
03:14	In the output window, go to the next slide using the green-coloured right arrow.
03:21	Look at the header portion of the pdf slide.
03:25	Section name “Beamer Themes” is seen on the left banner.
03:30	And the subsection name “Themes” is seen on the right banner.
03:37	These are the names we defined in the sections and subsections.
03:43	You can go to any slide by clicking on the section or subsection names.
03:50	Click on Color Themes on the top right banner.
03:55	The respective section name and subsection name of the slide you are on, get highlighted.
04:04	In my case, Beamer Themes and Color Themes get highlighted.
04:11	Let’s click on Introduction.
04:15	We are directed to the Introduction slide.
04:19	So, this part sort of behaves like a navigation panel.
04:25	Let’s go back to the code.
04:28	Beamer themes can be combined with a color theme.
04:32	To do so, before the begin document command, type the code as shown.
04:39	Always put the \usecolortheme command below the \usetheme command.
04:45	Now compile the file twice.
04:54	Observe the output.
04:56	colortheme command changed the color used for different elements.
05:01	Let’s go back to the code.
05:04	Let’s try another theme and theme color.
05:08	Update the \usetheme and \usecolortheme as shown.
05:14	I have set the theme to Madrid and the colortheme to crane.
05:21	Compile the file twice.
05:29	We can see the generated pdf output.
05:33	It has the Madrid theme along with the crane colortheme.
05:39	Next, we will see how to add Text Animation on the slides.
05:45	Overlay is a term used by the Beamer document class to describe the layering of slides.
05:54	There are a number of commands that enable us to use overlays on text.
06:02	Let’s see important overlays one by one.
06:07	Switch to the text editor.
06:10	Replace the document section code as shown here.
06:15	The number inside the angle brackets tells LaTeX which slides the item should appear on.
06:24	hyphen is used for continuation.
06:28	On compilation, we get the output as seen here.
06:33	In the generated pdf, click on the green right arrow to go to the next page.
06:40	Observe that our three lines of text are appearing one by one in a sequential order.
06:48	Switch to the editor once again.
06:51	Let’s make the text transparent on an unspecified slide.
06:57	Next to the line \frametitle type the code as shown here.
07:03	Compile the file.
07:05	Observe the output.
07:07	The upcoming slide texts appear as transparent text.
07:11	In the tex file, before the \end{document} command type the code as shown here.
07:18	Observe that here we have used \uncover instead of \onslide.
07:24	\uncover is with a digit present within angular brackets.
07:30	This will display the text on the slide depending on the number given here.
07:36	Notice that, here we have also changed the order of appearance of the text.
07:43	Compile the file
07:47	Using the navigation arrow, go to the slide Animation \uncover command.
07:54	Here only one out of five line items is appearing on the slide and the rest are transparent.
08:04	When you further navigate, it displays the third item instead of the second item.
08:11	This is because in the code the third item is mentioned as the second item.
08:17	And the second item is mentioned as the third item using the \uncover command.
08:25	In the tex file, before the \end{document} command, type the code as shown here.
08:32	The command \only works exactly like the \uncover command.
08:37	The only exception is that it does not reserve any space for the hidden text.
08:44	Compile the file.
08:47	Go to the slide Overlay: only command.
08:51	While navigating to the right, we can see only the respective item, and not the other items.
08:59	Also, all the items are appearing in the same line.
09:04	This is how we can customize LaTeX slides as per our requirement.
09:10	With this, we have come to the end of this tutorial. Let us summarize.
09:16	In this tutorial, we have learnt to: Add Beamer themes and color themes
09:23	Do text animations using Overlay
09:28	As an assignment, Add a new beamer theme Hannover and Color theme seahorse
09:37	To the file beamerThemesAndAnimation.tex
