Does anyone know how to increase the width of a floating table of content in rmarkdown so that it can show all titles in one line with no break.
Here is an example:
---
title: "Title"
author: "Author "
date: '`r format(Sys.Date(), "%B %d, %Y")`'
output:
html_document:
toc_float: true
toc: true
number_sections: true
code_folding: show
theme: lumen
editor_options:
chunk_output_type: console
---
# A loooooooooooooooooooooooong title
Thanks
What did the trick for me was to change the CSS style of the floating TOC. You can use a CSS code chunk to embed the CSS rules directly in your Rmd document. For example, like this:
title: "XY"
author: "XX"
date: '`r format(Sys.Date(), "%B %d, %Y")`'
output:
html_document:
toc: true
theme: united
toc_depth: 4
toc_float: true
.tocify .tocify-header {
position: fixed;
top: 50px;
left: 50px;
width: 500px;
height: 200px;
}
Or you can include this in a custom stylesheet:
output:
html_document:
css: "style.css"

I have encountered an issue with the size of banner title as in the following picture.
It is two-line title, which does not fit into the banner.
Is there any way to make the banner size bigger (vertically increased) or to make font size of title smaller.
I would appreciate it if you could show me both ways. Thanks.
My code is

To define CSS rule for a specific slide (It might be to change the title font size of that specific slide or to do anything), define a class: your-class-name just after creating a new slide with the ---.
So to change the title font size of that single slide, we write class: custom just after --- and then define CSS rule in css chunk for .custom to reduce the font-size.

# Heres another slide title
I was wondering if there is a simple way to do the change of font size, colour and style (bold, italic, etc.) for particular words or phrases in individual xaraingan slides within rmarkdown.
The following is my code:
---
title: "Econ"
subtitle: "Week 1"
author: "Instructor"
date: "`r Sys.Date()`"
output:
xaringan::moon_reader:
css: [default, metropolis, metropolis-fonts]
lib_dir: libs
nature:
highlightStyle: arta
highlightLines: true
countIncrementalSlides: false
---
# Is economics a science?
--
Probably not, maybe pseudo-science?.
I want to make "pseudo-science" bold, italicized, red, slightly bigger.
To style certain lines or phrases, you need to define your own content class (say .my-style) using CSS and wrap those lines or phrases with that content class (like .my-style[lines or phrases]) and define CSS rules for styles that you want to use in CSS file styles.css. Then attach that CSS file by specifying it in the YAML key css: along with other style files.
---
title: "Econ"
subtitle: "Week 1"
author: "Instructor"
date: "`r Sys.Date()`"
output:
xaringan::moon_reader:
css: [default, metropolis, metropolis-fonts, "styles.css"]
lib_dir: libs
nature:
highlightStyle: arta
highlightLines: true
countIncrementalSlides: false
---
# Is economics a science?
--
Probably not, maybe .my-style[pseudo-science]?.
styles.css
.my-style {
font-weight: bold;
font-style: italic;
font-size: 1.5em;
color: red;
}
For some reason,  does not work for me.
Any solution to fix this?
My yaml heading is the following:
---
title: "Econ"
subtitle: "Orientation and Lecture 1"
author: "Teacher"
institute: "University"
date: "`r Sys.Date()`"
output:
xaringan::moon_reader:
css: [default, metropolis, metropolis-fonts, "styles.css"]
lib_dir: libs
nature:
highlightStyle: arta
highlightLines: true
countIncrementalSlides: false

To scale an image in xaringan slides (in R-markdown), a safe option is using knitr::include_graphics along with chunk options.
```{r echo=FALSE, out.width="50%"}
knitr::include_graphics("test_animal.jpg")
```
Update
If you want to fill the entire slide with an image you can use background-image and background-size option in xaringan slides to do that.

I'm trying to convert a set of slides written in Rmarkdown and outputted in HTML with xaringan::moon_reader into PDF, and I used pagedown::chrome_print() to convert to PDF.
The issue is, the converted PDF has its title page missing as well as random pages throughout the slides. I tried to manually print the HTML file with Chrome and other browsers in an attempt to save to PDF, but they have the same missing pages.
I'm open to any advice on how to export to PDF without any pages missing. It doesn't have to be chrome_print() as long as the slides can be exported in PDF successfully.
Here's a reproducible pseudocode of the slides:
---
title: document_title
author: author_name
output:
xaringan::moon_reader:
css: [default, metropolis, metropolis-fonts]
lib_dir: libs
nature:

highlightLines: true
countIncrementalSlides: false

}
pre.sourceCode {
max-height: 200px;
overflow-y: auto;

.remark-slide-number .progress-bar-container {

display: block;

right: 0;
}
.remark-slide-number .progress-bar {
height: 100%;
background-color: blue;
}
*/
</style>
# only using two backticks for codechunks in rmd to escape ending the codeblock on stackoverflow

``{r setup, include=FALSE}

# Slide 1

2. Content 2

---
count: false
# Slide 2
</br>
.font130[
Content for slide 2
]
---
``{r gen_pdf, include = FALSE, cache = FALSE, eval = TRUE}
pagedown::chrome_print("slides.html", output = "slides.pdf")
``
We have count:true and count: false throughout the documents but it doesn't seem to relate to whether the page is missing or not.
Thank you so much in advance!
I've figured out what went wrong with my slides for anyone having the same issue:
So in the end it does have something to do with count: true or count: false
count: true indicates the start of a page, but count: false adds on new information on the same page on html format, but all the intermediate results are covered by whichever section that is your last count: false section.
An example would be :
---
count: true
Content 1
---
count: false
Content 2
---
count: false
Content 3
In this case Content 1 would be the start of a new page and everything will show up fine in .html, but on the pdf it was converted to, only Content 3 will show up, and not Content 1 or 2.
Title page was set to count: true automatically, but if you have a count: false section right after it, it will not show up.
Hopefully this explains it!
When I used \textsf{what} in the following document, "what" disappears in the output file. What should I do to prevent the problem while changing the font of "what"? Thanks!
title: "test"
author: test
date: 11/23/2020
link-citations: yes
output:
bookdown::html_document2: default

\textsf{what}
If you want to change the font when rendering to html output you colud use some inline CSS e.g.
<p style = "font-family: Times New Roman; color: red;">what</p>
will print "what" in red using Times New Roman.
I believe \textsf{what} is latex syntax, which is for PDF output. You are rendering to HTML in your example.
as the #stefan suggested inline CSS in your Rmarkdown it would look like this

title: "test"
author: test
date: 11/23/2020
link-citations: yes
output:
bookdown::html_document2: default
---
<style>
body, p {
background-color: lightgray;
color: black;
font-family: Arial Black;
}
</style>
what
I used Arial Black for the example to showcase the effects below.
