Advanced tools
A marked extension to support GFM footnotes.
You can install marked-footnote
using npm or yarn:
npm i marked-footnote
# or
yarn add marked-footnote
Once you've installed this extension, you can use it in your marked configuration. Here's an example of how to configure it:
Say we have the following file example.html
:
<!doctype html>
<html lang="en">
<head>
<meta charset="UTF-8" />
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
<title>Marked Footnote</title>

referrerpolicy="no-referrer"
/>
<style>
#content {
margin: 0 auto;
padding: 1rem;
max-width: 928px;
}
.sr-only {
position: absolute;
width: 1px;
height: 1px;
padding: 0;
overflow: hidden;
clip: rect(0, 0, 0, 0);
word-wrap: normal;
border: 0;
}
</style>
</head>
<body class="markdown-body">
<div id="content"></div>
<script src="https://cdn.jsdelivr.net/npm/marked/marked.min.js"></script>

<script>
const md = `# Example
[^1]: This is a footnote content.
Here is a simple footnote[^1]. With some additional text after it[^@#$%] and without disrupting the blocks[^bignote].
[^bignote]: The first paragraph of the definition.
Paragraph two of the definition.
> A blockquote with

| Header 1 | Header 2 |
| -------- | -------- |
| Cell 1 | Cell 2 |
A \`final\` paragraph before list.

- Item 2
- Subitem 1
- Subitem 2
[^@#$%]: A footnote on the label: "@#$%".
`
document.getElementById('content').innerHTML = new marked.Marked()
.use(markedFootnote())
.parse(md)
</script>
</body>
</html>
Say we have the following file example.md
:
# Example
[^1]: This is a footnote content.

| Header 1 | Header 2 |
| -------- | -------- |
| Cell 1 | Cell 2 |
A `final` paragraph before list.
- Item 1
- Item 2
- Subitem 1
- Subitem 2
[^@#$%]: A footnote on the label: "@#$%".
Note: The position of a footnote in your Markdown does not influence where the footnote will be rendered. You can write a footnote right after your reference to the footnote, and the footnote will still render at the bottom of the Markdown.
And our module example.js
looks as follows:
import { readFileSync } from 'node:fs'
import { Marked } from 'marked'
import markedFootnote from 'marked-footnote'
const html = new Marked()
.use(markedFootnote())
.parse(readFileSync('example.md', 'utf8'))
console.log(html)
Now, running node example.js
yields:
<h1>Example</h1>
<p>
Here is a simple footnote<sup
><a
id="footnote-ref-1"
href="#footnote-1"
data-footnote-ref
aria-describedby="footnote-label"
>1</a
></sup
>. With some additional text after it<sup
><a
id="footnote-ref-%40%23%24%25"
href="#footnote-%40%23%24%25"
data-footnote-ref
aria-describedby="footnote-label"
>2</a
></sup
>
and without disrupting the blocks<sup
><a
id="footnote-ref-bignote"
href="#footnote-bignote"
data-footnote-ref
aria-describedby="footnote-label"
>3</a
></sup
>.

By default, this plugin does not place footnote markers in square brackets ([1]
), instead like this: 1
. So you will need to add the style as shown below to your CSS:
[data-footnote-ref]::before {
content: '[';
}
[data-footnote-ref]::after {
content: ']';
}
The marked-footnote extension accepts the following configuration options:
prefixId
: The prefix ID for footnotes. Defaults to 'footnote-'
.
description
: The description of footnotes, used by aria-labeledby
attribute. Defaults to 'Footnotes'
.
refMarkers
: If set to true
, it will place footnote reference in square brackets, like this: [1]
. Defaults to false
.
When considering the use of footnotes in your content, it's important to keep in mind the following accessibility and usability factors:
