# Callouts

Callouts use Obsidian-compatible blockquote syntax and keep normal Markdown
available inside their bodies.

> [!note]
> A general note with a default title.

> [!abstract] Summary
> A compact overview of the material that follows.

> [!info] Rich content
> Callouts support **inline formatting**, links, and lists:
>
> - One useful detail
> - Another useful detail

> [!todo]
>
> - [x] Shape the authoring syntax
> - [ ] Write the next lesson

> [!tip] A practical tip
> Put the most actionable idea here.

> [!success]
> The operation completed successfully.

> [!question]+ Can callouts be nested?
> Yes. Foldable callouts use native disclosure controls.
>
> > [!example] Nested example
> > This callout is inside the question callout.

> [!warning]
> Check the assumptions before continuing.

> [!failure]
> The expected result was not produced.

> [!danger]- Destructive operation
> This content starts collapsed.

> [!bug]
> Record enough detail to reproduce the problem.

> [!quote]
> Simplicity is a feature.

> [!custom-question] Custom type
> Unknown identifiers keep their own `data-callout` hook and use the note
> appearance as a safe fallback.

> [!tip] Title-only callout
