Admonitions

Admonitions, also known as call-outs, are an excellent choice for including side content without significantly interrupting the document flow. Material for MkDocs provides several different types of admonitions and allows for the inclusion and nesting of arbitrary content.

Configuration

This configuration enables admonitions, allows to make them collapsible and to nest arbitrary content inside admonitions. Add the following lines to mkdocs.yml:

markdown_extensions:
  - admonition
  - pymdownx.details
  - pymdownx.superfences

See additional configuration options:

Admonition icons

8.3.0

Each of the supported admonition types has a distinct icon, which can be changed to any icon bundled with the theme, or even a custom icon. Add the following lines to mkdocs.yml:

theme:
  icon:
    admonition:
      <type>: <icon> # (1)!
  1. Enter a few keywords to find the perfect icon using our icon search and click on the shortcode to copy it to your clipboard:

    Usage

    Admonitions follow a simple syntax: a block starts with !!!, followed by a single keyword used as a type qualifier. The content of the block follows on the next line, indented by four spaces:

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

    Note

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

    Changing the title

    By default, the title will equal the type qualifier in titlecase. However, it can be changed by adding a quoted string containing valid Markdown (including links, formatting, ...) after the type qualifier:

    Admonition with custom title
    !!! note "Phasellus posuere in sem ut cursus"
    
        Lorem ipsum dolor sit amet, consectetur adipiscing elit. Nulla et euismod
        nulla. Curabitur feugiat, tortor non consequat finibus, justo purus auctor
        massa, nec semper lorem quam in massa.
    

    Phasellus posuere in sem ut cursus

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

    Removing the title

    Similar to changing the title, the icon and title can be omitted entirely by adding an empty string directly after the type qualifier. Note that this will not work for collapsible blocks:

    Admonition without title
    !!! note ""
    
        Lorem ipsum dolor sit amet, consectetur adipiscing elit. Nulla et euismod
        nulla. Curabitur feugiat, tortor non consequat finibus, justo purus auctor
        massa, nec semper lorem quam in massa.
    

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

    Collapsible blocks

    When Details is enabled and an admonition block is started with ??? instead of !!!, the admonition is rendered as a collapsible block with a small toggle on the right side:

    Admonition, collapsible
    ??? note
    
        Lorem ipsum dolor sit amet, consectetur adipiscing elit. Nulla et euismod
        nulla. Curabitur feugiat, tortor non consequat finibus, justo purus auctor
        massa, nec semper lorem quam in massa.
    
    Note

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

    Adding a + after the ??? token renders the block expanded:

    Admonition, collapsible and initially expanded
    ???+ note
    
        Lorem ipsum dolor sit amet, consectetur adipiscing elit. Nulla et euismod
        nulla. Curabitur feugiat, tortor non consequat finibus, justo purus auctor
        massa, nec semper lorem quam in massa.
    
    Note

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

    Inline blocks

    Admonitions can also be rendered as inline blocks (e.g., for sidebars), placing them to the right using the inline + end modifiers, or to the left using only the inline modifier:

    Lorem ipsum

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

    !!! info inline end "Lorem ipsum"
    
        Lorem ipsum dolor sit amet, consectetur
        adipiscing elit. Nulla et euismod nulla.
        Curabitur feugiat, tortor non consequat
        finibus, justo purus auctor massa, nec
        semper lorem quam in massa.
    

    Use inline end to align to the right (left for rtl languages).

    Lorem ipsum

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

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

    Use inline to align to the left (right for rtl languages).

    Important: admonitions that use the inline modifiers must be declared prior to the content block you want to place them beside. If there's insufficient space to render the admonition next to the block, the admonition will stretch to the full width of the viewport, e.g., on mobile viewports.

    Customization

    Classic admonitions

    Prior to version 8.5.6, admonitions had a slightly different appearance:

    Note

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

    If you want to restore this appearance, add the following CSS to an additional style sheet:

    .md-typeset .admonition,
    .md-typeset details {
      border-width: 0;
      border-left-width: 4px;
    }
    
    extra_css:
      - stylesheets/extra.css
    

    Custom admonitions

    If you want to add a custom admonition type, all you need is a color and an *.svg icon. Copy the icon's code from the .icons folder and add the following CSS to an additional style sheet:

    :root {
      --md-admonition-icon--pied-piper: url('data:image/svg+xml;charset=utf-8,<svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 576 512"><path d="M244 246c-3.2-2-6.3-2.9-10.1-2.9-6.6 0-12.6 3.2-19.3 3.7l1.7 4.9zm135.9 197.9c-19 0-64.1 9.5-79.9 19.8l6.9 45.1c35.7 6.1 70.1 3.6 106-9.8-4.8-10-23.5-55.1-33-55.1zM340.8 177c6.6 2.8 11.5 9.2 22.7 22.1 2-1.4 7.5-5.2 7.5-8.6 0-4.9-11.8-13.2-13.2-23 11.2-5.7 25.2-6 37.6-8.9 68.1-16.4 116.3-52.9 146.8-116.7C548.3 29.3 554 16.1 554.6 2l-2 2.6c-28.4 50-33 63.2-81.3 100-31.9 24.4-69.2 40.2-106.6 54.6l-6.3-.3v-21.8c-19.6 1.6-19.7-14.6-31.6-23-18.7 20.6-31.6 40.8-58.9 51.1-12.7 4.8-19.6 10-25.9 21.8 34.9-16.4 91.2-13.5 98.8-10zM555.5 0l-.6 1.1-.3.9.6-.6zm-59.2 382.1c-33.9-56.9-75.3-118.4-150-115.5l-.3-6c-1.1-13.5 32.8 3.2 35.1-31l-14.4 7.2c-19.8-45.7-8.6-54.3-65.5-54.3-14.7 0-26.7 1.7-41.4 4.6 2.9 18.6 2.2 36.7-10.9 50.3l19.5 5.5c-1.7 3.2-2.9 6.3-2.9 9.8 0 21 42.8 2.9 42.8 33.6 0 18.4-36.8 60.1-54.9 60.1-8 0-53.7-50-53.4-60.1l.3-4.6 52.3-11.5c13-2.6 12.3-22.7-2.9-22.7-3.7 0-43.1 9.2-49.4 10.6-2-5.2-7.5-14.1-13.8-14.1-3.2 0-6.3 3.2-9.5 4-9.2 2.6-31 2.9-21.5 20.1L15.9 298.5c-5.5 1.1-8.9 6.3-8.9 11.8 0 6 5.5 10.9 11.5 10.9 8 0 131.3-28.4 147.4-32.2 2.6 3.2 4.6 6.3 7.8 8.6 20.1 14.4 59.8 85.9 76.4 85.9 24.1 0 58-22.4 71.3-41.9 3.2-4.3 6.9-7.5 12.4-6.9.6 13.8-31.6 34.2-33 43.7-1.4 10.2-1 35.2-.3 41.1 26.7 8.1 52-3.6 77.9-2.9 4.3-21 10.6-41.9 9.8-63.5l-.3-9.5c-1.4-34.2-10.9-38.5-34.8-58.6-1.1-1.1-2.6-2.6-3.7-4 2.2-1.4 1.1-1 4.6-1.7 88.5 0 56.3 183.6 111.5 229.9 33.1-15 72.5-27.9 103.5-47.2-29-25.6-52.6-45.7-72.7-79.9zm-196.2 46.1v27.2l11.8-3.4-2.9-23.8zm-68.7-150.4l24.1 61.2 21-13.8-31.3-50.9zm84.4 154.9l2 12.4c9-1.5 58.4-6.6 58.4-14.1 0-1.4-.6-3.2-.9-4.6-26.8 0-36.9 3.8-59.5 6.3z"/></svg>')

    After applying the customization, you can use the custom admonition type:

    Admonition with custom type
    !!! pied-piper "Pied Piper"
    
        Lorem ipsum dolor sit amet, consectetur adipiscing elit. Nulla et
        euismod nulla. Curabitur feugiat, tortor non consequat finibus, justo
        purus auctor massa, nec semper lorem quam in massa.
    

    Pied Piper

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


    1. Previously, some of the supported types defined more than one qualifier. For example, authors could use summary or tldr as alternative qualifiers to render an abstract admonition. As this increased the size of the CSS that is shipped with Material for MkDocs, the additional type qualifiers are now all deprecated and will be removed in the next major version. This will also be mentioned in the upgrade guide.
