How to Use Call-Out Boxes

Call-out boxes are highlighted content blocks used to draw attention to important information, tips, warnings, or any content that should stand out from the main text.

What Can Go Inside a Call-Out Box

Call-out boxes aren’t limited to plain text. You can place most elements inside them to add borders around:

Blockquotes: Give quoted text extra visual emphasis
Images: Frame photos or illustrations with a border
Handwriting: Highlight letters, notes, or diary entries

This flexibility lets you create bordered sections for any content that needs to stand out.

Customizing Your Call-Out Box

Select a call-out box to open its style panel. It has three tabs: Border, Styling, and Spacing.

Border

Thickness. The border width on each side.
Line Style. Solid, Dashed, or Dotted.
Radius. How rounded the corners are.

Styling

Colors. A Background color and a Text Color, each from a color picker (leave on Default to use your theme color).
Line Height. The space between lines of text inside the box.

Spacing

Around Callout Box. The space on all four sides, outside the box.
Inside Callout Box. The padding between the border and the content.
Trim Top Spacing on Page Start. When the box lands at the top of a new page in print, removes the space above it so it sits flush with the top margin. (Print only.)

Using Presets

You can save and reuse call-out box styles with presets. This makes it easy to apply consistent border styles across all call-out boxes in your book.

Finding Call-Out Boxes

Use the Elements tab in the section sidebar to find all call-out boxes in your book and jump directly to any of them.
