Admonitions
mdbook-spec provides admonitions that use a style similar to GitHub-flavored Markdown. The style name is placed at the beginning of a blockquote, such as:
> [!WARNING]
> This is a warning.
> [!NOTE]
> This is a note.
> [!EDITION-2024]
> This is an edition-specific difference.
> [!EXAMPLE]
> This is an example.
The color and styling are defined in theme/reference.css and the transformation and icons are in tools/mdbook-spec/src/admonitions.rs.
See Conventions in the Reference introduction for a description of how these should be used.
