Callouts, or "admonitions", highlight a particular block of text that exists slightly apart from the narrative of your page, such as a note or a warning. For example, try changing the following example of a {tip} admonition to a {warning}:

In MyST we call these kind of directives admonitions, however, they are almost always used through their named directives, like {note} or {danger}. Admonitions can be styled as simple or as a dropdown, and can optionally hide the icon using the class option. There are ten kinds[1] of admonitions available:

Admonition TitlesΒΆ

All admonitions have a single argument (docs), which is the admonition title and can use markdown. If a title argument is not supplied the first node of the body is used if it is a heading or a paragraph with fully bold text; otherwise the name of the directive is used (e.g. seealso becomes See Also; note becomes Note).

Compatibility with GitHub

GitHub markdown transforms blockquotes that start with a bold Note or text with [!NOTE] into a simple admonition (see GitHub). This syntax only works for note, important or warning. MyST transforms these blockquotes into the appropriate admonitions with a simple class.

Compatibility with Pandoc & Quarto

In Quarto/Pandoc markdown admonitions are styled with special classes like {.callout-note} or {.callout-tip}). If you are using JupyterBook or Sphinx documentation, use an {admonition} directive with the specific class, for example:

Compatibility with Sphinx

In Sphinx, all named admonitions (e.g. {note} or {tip}), have no arguments. If you place content on the first line it will instead be prepended to the admonition body. If you are using JupyterBook or Sphinx documentation, use an {admonition} directive with the specific class, for example:

Admonition DropdownΒΆ

To turn an admonition into a dropdown, add the dropdown class to them. Dropdown admonitions use the <details> HTML element (meaning they also will work without Javascript!), and they can be helpful when including text that shouldn't immediately visible to your readers.

You can also use a {dropdown}

You can also use a dropdown directive, which provides a more compact writing experience and is simpler in the displayed style. See Dropdowns for more information.
