Callouts (also sometimes referred to as alerts, info boxes, or banners) allow you to draw attention to specific content within an item. It's a great way to provide explanations, notes, hints, warnings, or other important context.

There are five different callout styles you can choose from:

You can freely customize the title and content of a callout, making it as simple or as detailed as you need.
