Annotations

One of the flagship features of Material for MkDocs is the ability to inject annotations – little markers that can be added almost anywhere in a document and expand a tooltip containing arbitrary Markdown on click or keyboard focus.

Configuration

This configuration allows to add annotations to all inline- and block-level elements, as well as code blocks, and nest annotations inside each other. Add the following lines to mkdocs.yml:

markdown_extensions:
  - attr_list
  - md_in_html
  - pymdownx.superfences

See additional configuration options:

• Attribute Lists
• Markdown in HTML
• SuperFences

Usage

Using annotations

:octicons-heart-fill-24:{ .mdx-heart } Sponsors only{ .mdx-insiders } · :octicons-tag-24: insiders-4.6.0 · :octicons-beaker-24: Experimental

Annotations consist of two parts: a marker, which can be placed anywhere in a block marked with the annotate class, and content located in a list below the block containing the marker:

Lorem ipsum dolor sit amet, (1) consectetur adipiscing elit.
{ .annotate }

1.  :man_raising_hand: I'm an annotation! I can contain `code`, __formatted
    text__, images, ... basically anything that can be expressed in Markdown.

Lorem ipsum dolor sit amet, (1) consectetur adipiscing elit. { .annotate }

1. :man_raising_hand: I'm an annotation! I can contain code, formatted text, images, ... basically anything that can be written in Markdown.

Note that the annotate class must only be added to the outermost block. All nested elements can use the same list to define annotations, except when annotations are nested themselves.

in annotations

When SuperFences is enabled, annotations can be nested inside annotations by adding the annotate class to the list item hosting the annotation content, repeating the process:

Lorem ipsum dolor sit amet, (1) consectetur adipiscing elit.
{ .annotate }

1.  :man_raising_hand: I'm an annotation! (1)
    { .annotate }

    1.  :woman_raising_hand: I'm an annotation as well!

Lorem ipsum dolor sit amet, (1) consectetur adipiscing elit. { .annotate }

1. :man_raising_hand: I'm an annotation! (1) { .annotate style="margin-bottom: 0" }

   1. :woman_raising_hand: I'm an annotation as well!

in admonitions

The titles and bodies of admonitions can also host annotations by adding the annotate modifier after the type qualifier, which is similar to how inline blocks work:

!!! note annotate "Phasellus posuere in sem ut cursus (1)"

    Lorem ipsum dolor sit amet, (2) consectetur adipiscing elit. Nulla et
    euismod nulla. Curabitur feugiat, tortor non consequat finibus, justo
    purus auctor massa, nec semper lorem quam in massa.

1.  :man_raising_hand: I'm an annotation!
2.  :woman_raising_hand: I'm an annotation as well!

!!! note annotate "Phasellus posuere in sem ut cursus (1)"

Lorem ipsum dolor sit amet, (2) consectetur adipiscing elit. Nulla et
euismod nulla. Curabitur feugiat, tortor non consequat finibus, justo
purus auctor massa, nec semper lorem quam in massa.

1. :man_raising_hand: I'm an annotation!
2. :woman_raising_hand: I'm an annotation as well!

in content tabs

Content tabs can host annotations by adding the annotate class to the block of a dedicated content tab (and not to the container, which is not supported):

=== "Tab 1"

    Lorem ipsum dolor sit amet, (1) consectetur adipiscing elit.
    { .annotate }

    1.  :man_raising_hand: I'm an annotation!

=== "Tab 2"

    Phasellus posuere in sem ut cursus (1)
    { .annotate }

    1.  :woman_raising_hand: I'm an annotation as well!

=== "Tab 1"

Lorem ipsum dolor sit amet, (1) consectetur adipiscing elit.
{ .annotate }

1.  :man_raising_hand: I'm an annotation!

=== "Tab 2"

Phasellus posuere in sem ut cursus (1)
{ .annotate }

1.  :woman_raising_hand: I'm an annotation as well!

in everything else

The Attribute Lists extension is the key ingredient for adding annotations to most elements, but it has some limitations. However, it's always possible to leverage the Markdown in HTML extension to wrap arbitrary elements with a div with the annotate class:

<div class="annotate" markdown>

> Lorem ipsum dolor sit amet, (1) consectetur adipiscing elit.

</div>

1.  :man_raising_hand: I'm an annotation!

Lorem ipsum dolor sit amet, (1) consectetur adipiscing elit.

1. :man_raising_hand: I'm an annotation!

With this trick, annotations can also be added to blockquotes, lists, and many other elements that are not supported by the Attribute Lists extension. Furthermore, note that code blocks follow different semantics.

!!! warning "Known limitations"

Please note that annotations currently don't work in [data tables] as
reported in #3453, as data tables are scrollable elements and positioning
is very tricky to get right. This might be fixed in the future.
