Key points
Callouts are a way of highlighting important information in articles. They can also be used to separate relevant but not clearly related content from the content adjacent to it.
Callouts appear as shaded boxes in the body copy.
Callouts should be kept concise and to the point.
Callouts are best positioned at the end of a section, not in the middle. Do not put them directly underneath the introduction field, except in very rare circumstances.
There are several callout styles, which can be used to highlight different types of content.
The most commonly used callout style is the asterisk (used for general information).
