Callouts

Callouts are styled blockquotes that visually distinguish different types of information in your notes. They are rendered with a colored left border, an icon, and a title. Noteriv supports 14 callout types, each with a distinct color and icon.

Syntax

A callout is a blockquote with a type identifier on the first line:

> [!type] Optional Title
> Content of the callout.
> Can span multiple lines.

The [!type] marker must be the first thing on the first line of the blockquote. The title after the type is optional. If omitted, the type name is used as the title (capitalized).

Collapsible Callouts

You can make callouts collapsible by adding - or + after the type identifier:

Initially Collapsed

> [!tip]- Click to Expand
> This content is hidden by default.
> Click the callout title to reveal it.

The - after [!tip] means the callout starts collapsed. The user must click the title to expand it and see the content.

Initially Expanded

> [!tip]+ Click to Collapse
> This content is visible by default.
> Click the callout title to collapse it.

The + after [!tip] means the callout starts expanded but can be collapsed by clicking the title.

Non-Collapsible (Default)

> [!tip] Always Visible
> This callout has no collapse behavior.

Without - or +, the callout is always expanded and cannot be collapsed.

Nesting Content

Callouts can contain any markdown content, including:

• Paragraphs
• Lists (ordered, unordered, task lists)
• Code blocks
• Images
• Links and wiki-links
• Math (inline and block)
• Other blockquotes

> [!example] Complex Callout
> Here is a list inside a callout:
>
> - Item one
> - Item two
>   - Nested item
>
> And a code block:
>
> ```python
> def hello():
>     print("Hello from a callout!")
> ```
>
> And some math: $E = mc^2$

Callout Color Reference

Because callout colors use theme CSS variables, they adapt automatically to your active theme. A "danger" callout in Catppuccin Mocha uses a different shade of red than in Solarized Dark, but both are clearly identifiable as danger callouts.

Custom Callout Styling

You can customize callout appearance using CSS snippets. For example, to add rounded corners to all callouts:

.callout {
  border-radius: 8px;
  overflow: hidden;
}

Or to change the color of a specific callout type:

.callout-tip {
  border-left-color: #ff9900;
}

See CSS Snippets for more details on creating and managing snippets.
