Callouts are styled boxes that sit inside the flow of a lesson page. They're useful for examples, warnings, definitions or anything else worth flagging.
Adding one
Type / and start typing the kind you want. Or click + in the left margin and pick from the Callout group.
You'll see six presets:
Callout: a neutral box for general "look here" content
Example: for worked examples
Key term: for definitions
Tip: for advice and suggestions
Warning: for things students need to be careful of
Note: for asides
Each one has a sensible default colour, header tone and left border.
Editing the look
Click the handle to the left of a callout to open its style dropdown. From there you can change:
Accent colour (the swatch grid)
Background tone
Header tone
Left border on or off
The presets are starting points, not restrictions. A Tip callout can be repainted to look like a Warning if you want.
What goes inside
Callouts hold paragraphs, lists, bold, italic, links and inline math. They don't hold questions, videos or other callouts, so if you need an interactive question to draw attention to itself, drop a Callout above or below it.
Heading
Each callout has a header line. Leave it blank for callouts that don't need a label, or use it for the word "Example", "Definition", or whatever fits the content.
