Looking to make check boxes in Rmarkdown, I found this link, but trying to avoid latex. on the Rmarkdown cheatsheet there isn't a checkbox example. but the code below is markdown, but doesn't render.
---
title: "Untitled"
author: "Daniel"
date: "6/13/2020"
output: html_document
---
```{r}
```
- [ ] Venus
- [x] Mars
It is possible to use raw HTML code to do that:
- <input type="checkbox" unchecked> Venus</input>
- <input type="checkbox" checked> Mars</input>
This will render to:

## R Markdown
When you click the **Knit** button a document will be generated that includes both content as well as the output of any embedded R code chunks within the document.
## Slide with Bullets
- Bullet 1
- Bullet 2
- Bullet 3
but this did not work.
The lower left Contents could be changed to Inhalts using javascript code (sort of Brute-force way)

everything works file.

While there seems to be quite a bit of discussion about this (here, here, here), it is not clear how one could remove the section heading auto_identifiers (the "#" that appears after a slide's section header; h1,h2,etc.) from a Xaringan theme in Rmarkdown.
Can this be done within the YAML? (markdown: kramdown seems to have an auto_ids: false addition to the header as shown here)
Can this be done in a custom.css by editing .h1 etc.?
Similar to this post:
If the headers are specified as:
# header1 {#header1id}
## header2
### header3
The resulting HTML:
<h1 id="header1id">header1</h1>
<h2 id="header2">header2</header2>
<h3 id="header3">header3</header3>
But I would prefer:
<h1 id="header1id">header1</h1>
<h2>header2</h2>
<h3>header3</h3>
Obviously, using the html directly works (e.g., <h1>header1</h1>), but it would be great to be able to use the markdown # headers.
For completeness, an example YAML within a Rmarkdown.Rmd Xaringan template:

title: "Please Remove the # Anchors"
author: "Begin Er"
date: "Now"
output:
xaringan::moon_reader:
css: [default, metropolis, metropolis-fonts]

Thanks!
I am currently creating my own pandoc template for Rmarkdown (outputting html). I want my report to show a footer containing the title and first author's name.
Reading the pandoc manual, I saw that it is possible to use a pipe to get the first element of an array (var/first). So having the header:
title: "My Report"
author:
- "Jane Doe"
- "John Doe"
I tried to do the following in the template:
<div class="footer">
<div class="footer-content">
<div class="footer-title">
<h3>$title$</h3>
</div>
<div class="footer-author">
<h3>$author/first$</h3>
</div>
</div>
</div>
Then I got as error in the author line:
"template" (line 96, column 24):
unexpected "/"
expecting "." or "$"
Please note that the pandoc version used by rmarkdown is 2.3.1.
Is there a different way to accomplish that?
You could write a small Lua filter to get just the first author:
function Meta (meta)
local firstauthor = meta.author.t == 'MetaList'
and meta.author[1]
or meta.author
meta.firstauthor = firstauthor
return meta
end
You can then use $firstauthor$ in your template. See here for a brief discussion of Lua filters and how to use them.
I'm trying to insert a Gantt diagram in my Rmarkdown, using DiagrammeR mermaid.
The problem is when I knit to html, my text appears all greyish/transparent.
I noticed that when I remove the ## for headers, everything's fine.
Does anyone have a solution for me?
Here's the code template :
---
title: "My title"
author: "J. Doe"
output:
html_document:
toc: no
bibliography: biblio.bib

```{r libraries, include=FALSE}
library(DiagrammeR)```
```{r setup, include=FALSE}
knitr::opts_chunk$set(echo = TRUE)```
<style>
body {
text-align: justify}
</style>
## Table of content
1. [Project objectives](#bullet-1)
2. [Done and current tasks](#bullet-2)
3. [Bibliography](#bullet-3)
## 1. <a class="anchor" id="bullet-1"></a> Project objectives

## 3. BIBLIOGRAPHY
Many thanks!
J.
The example below (i.e. saved as a file index.rmd ) has the same code chunk to display an image above and below the top level heading, but the image doesn't appear above the top level heading. This occurs if there is a file _output.yml with only this entry bookdown::gitbook: in the same directory.
That line seems to enforce a table of contents (which I want) and that appears to strip out anything (image or text) before the first top level heading by default (which I don't want) - so can this behaviour be modified?

# R Markdown
```{r echo=FALSE, message=FALSE, warning=FALSE}
library(imager)
im <- load.image(system.file('extdata/Leonardo_Birds.jpg',package='imager'))
plot(im, axes=FALSE)
```
What follows is workaround to your Options 2 and 3, using Markdown and CSS to style images and HTML+CSS to style text; also, using base64 image (transparent gif) generator as an space separator between elements.
Beware of whitespaces! (at the end of each line - place two white spaces and hit ENTER)
Does one of these approaches/hacks work for you? If not, it would be better to delete the answer, it may be misleading to others.

Using Markdown table to "style" images |-| (left-aligned), |:-:| (centered) and |-:| (right-aligned) will work well with simple RMarkdown outputs.
I realised that you have an image under # top level heading positioned at the very top of the page - with top:0px. causing image duplication and, possibly, hover problem:
<img src="https://i.imgur.com/GiViTbA.png" style="position:absolute;top:0px;height:100px;" />
replace with:
{width=50px style="display: block; margin:0 auto;"}
and see what will happen.

R Markdown Title
{width=50px}
output:

---
# I'm a top level heading {-}
{width=50px style="display: block; margin:0 auto;"}
Note, you need to replace the image with a local image if you want to show the image in the rstudio viewer.
The image will be visible in the html file created when you knit, if you open in a browser connected to the internet.

EDIT:
Let's try to find a common ground, A Minimal Book Example, github here.
Adjustments made in index.Rmd:
---
title: |
{height=300px}
author: "Author Name"
date: "`r Sys.Date()`"
site: bookdown::bookdown_site
output: bookdown::gitbook

# Prerequisites
<img src="https://i.imgur.com/GiViTbA.png" style="position:absolute;top:50px;height:300px;align:center;" />
This is a _sample_ book written in **Markdown**. You can use anything that Pandoc's Markdown supports, e.g., a math equation $a^2 + b^2 = c^2$.
index.Rmd output:
Adjustments made in Chapter: Introduction (01-intro.Rmd):
# Introduction {#intro}
{height=240px}
<img src="https://i.imgur.com/GiViTbA.png" style="position:absolute;top:50px;height:300px;align:center;" />
You can label chapter and section titles using `{#label}` after them, e.g., we can reference Chapter \#ref(intro). If you do not manually label them, there will be automatic labels anyway, e.g., Chapter \#ref(methods).
01-intro.Rmd output:
With this solution we are "masking" a top level heading (# Introduction) with .png image, which will appear in the Table of Content as text.
Disadvantage: besides the obvious hack, image width must be at least equal or wider than top level heading title.
Note: 3 options are provided here, and none of them are perfect. The perfect solution may rely on modifications to the bookdown package?
Option 1:
Use includes with before_body like this in your _output.yml file (suggested here):
bookdown::gitbook:
css: assets/style.css
includes:
before_body: assets/big-image.html
after_body: assets/footer.html
Disadvantages:
i) Requires making a html file just to insert an image.
ii) If using a web-based image, won't show in Rstudio viewer.
iii) If using a local image, path can get mixed up and won't show in online web html rendering
iv) Includes image at the top of each chapter of bookdown if using before_body: my_image.html. Alternative option in_header: my_image.html does not seem compatible with the sidebar index.
Option 2
Insert image via yaml in index.rmd, using the solution under Tip 3 Add a Logo in your title/header/footer at this blog post
---
title: |
My title
Disadvantages:
i) When you hover over the image, it displays a copy of the image in a slightly different location (Can this "Hover" behaviour be disabled?)
ii) If using a web-based image, won't show in Rstudio viewer.
iii) If using a local image, path can get mixed up and won't show in online web html rendering
Option 3
The code below borrowed from here (which you can place below the top level heading) presumably goes direct through the knitting process and inserts itself in the final html. The issue is that the image doesn't make room for itself and ends up over the first text. Is there some simple html/css to sort this out?
<img src="https://i.imgur.com/GiViTbA.png" style="position:absolute;top:0px;height:100px;" />
Disadvantages:
i) Image doesn't make room for itself and ends up over the first text. You can get around this with a hack by coding extra space (trial and error) through the yaml title like this:
title: |

EDIT
This is superseded by Radovan's accepted answer.
This was the best answer, taking option 3 from my previous answer, and combining a code approach to making the relevant space from Radovan's answer.
You will still have problems if you want to include a title in the YAML (I don't need this, as my title is in the image).
Also, on first loading the page, it presents nicely, but image is not seen if you go to the top of the document using the table of contents (the inheader approach used by this bookdown shows a better behaviour, but appears at the top of every chapter, which is not desired).

The problem of hovering the image duplicating the image can be fixed by removing the line below from the css file that is generated at \libs\gitbook-2.6.7\css\style.css
.book .book-header h1 a:hover{color:inherit;text-decoration:none}#media (max-width:1000px){.book .book-header h1{display:none}}
as a result, this code below places the image right above the title:
