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:-

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.
