sidenote becomes footnote

[linlennypinawa]

I copied and pasted the content to an external css file. My simplest rmd is as follows:

---
title: "Untitled"
author: "John Doe"
date: "2022-12-07"
output: 
  html_document:
    css: css\tufte_original.css
---



## R Markdown

This is an R Markdown document. Markdown is a simple formatting syntax for authoring HTML, PDF, and MS Word documents.  For more details on using R Markdown see <http://rmarkdown.rstudio.com>. ^[test1]

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. You can embed an R code chunk like this: ^[test2]

Just realize that I have to add tufte::tufte_html: default in yaml to get the footnote to the sidenote. I do not need the following section of yaml.

html_document:
    css: css\tufte_original.css

It was my intention to implement the tufte style to my blog through blogdown with hugo theme. I have no problem with margin note, but when getting side note, I get it, but the number is 0.
