# Quarto Presentations

Create beautiful interactive slide decks with Reveal.js

## Hello, There

This presentation will show you examples of what you can do with Quarto and Reveal.js, including:

• Presenting code and LaTeX equations
• Including computations in slide output
• Image, video, and iframe backgrounds
• Fancy transitions and animations
• Printing to PDF

…and much more

## Pretty Code

• Over 20 syntax highlighting themes available
• Default theme optimized for accessibility
# Define a server for the Shiny app
function(input, output) {

# Fill in the spot we created for a plot
output$phonePlot <- renderPlot({ # Render a barplot }) } ## Code Animations • Over 20 syntax highlighting themes available • Default theme optimized for accessibility # Define a server for the Shiny app function(input, output) { # Fill in the spot we created for a plot output$phonePlot <- renderPlot({
# Render a barplot
barplot(WorldPhones[,input$region]*1000, main=input$region,
ylab="Number of Telephones",
xlab="Year")
})
}

## Line Highlighting

• Highlight specific lines for emphasis
import numpy as np
import matplotlib.pyplot as plt

r = np.arange(0, 2, 0.01)
theta = 2 * np.pi * r
fig, ax = plt.subplots(subplot_kw={'projection': 'polar'})
ax.plot(theta, r)
ax.set_rticks([0.5, 1, 1.5, 2])
ax.grid(True)
plt.show()

## Executable Code

library(ggplot2)
ggplot(mtcars, aes(hp, mpg, color = am)) +
geom_point() +
geom_smooth(formula = y ~ x, method = "loess")

## LaTeX Equations

MathJax rendering of equations to HTML

\begin{gather*}
a_1=b_1+c_1\\
a_2=b_2+c_2-d_2+e_2
\end{gather*}

\begin{align}
a_{11}& =b_{11}&
a_{12}& =b_{12}\\
a_{21}& =b_{21}&
a_{22}& =b_{22}+c_{22}
\end{align}
$\begin{gather*} a_1=b_1+c_1\\ a_2=b_2+c_2-d_2+e_2 \end{gather*}$ \begin{align} a_{11}& =b_{11}& a_{12}& =b_{12}\\ a_{21}& =b_{21}& a_{22}& =b_{22}+c_{22} \end{align}

## Column Layout

Arrange content into columns of varying widths:

#### Motor Trend Car Road Tests

The data was extracted from the 1974 Motor Trend US magazine, and comprises fuel consumption and 10 aspects of automobile design and performance for 32 automobiles.

mpg cyl disp hp wt
Mazda RX4 21.0 6 160 110 2.620
Mazda RX4 Wag 21.0 6 160 110 2.875
Datsun 710 22.8 4 108 93 2.320
Hornet 4 Drive 21.4 6 258 110 3.215

## Incremental Lists

Lists can optionally be displayed incrementally:

• First item
• Second item
• Third item

Insert pauses to make other types of content display incrementally.

## Fragments

Incremental text display and animation with fragments:

Strike

Highlight red

## Slide Backgrounds

Set the background attribute on a slide to change the background color (all CSS color formats are supported).

Different background transitions are available via the background-transition option.

## Media Backgrounds

You can also use the following as a slide background:

• An image: background-image

• A video: background-video

• An iframe: background-iframe

## Absolute Position

Position images or other elements at precise locations

## Auto-Animate

Automatically animate matching elements across slides with Auto-Animate.

## Auto-Animate

Automatically animate matching elements across slides with Auto-Animate.

## Slide Transitions

The next few slides will transition using the slide transition

Transition Description
none No transition (default, switch instantly)
fade Cross fade
slide Slide horizontally
convex Slide at a convex angle
concave Slide at a concave angle
zoom Scale the incoming slide so it grows in from the center of the screen.
