# Callouts

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. There are ten kinds of admonitions available:

See below for a demo of each admonition in the default theme.

Note
Important
Hint
Tip
Attention
Caution
Warning
Danger
Error

All admonitions have a single argument, which is the admonition title and can use markdown. If a title argument is not supplied the first node 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 Warning into a simple admonition (see GitHub). MyST also 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:

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 for more information.
