Callouts are typically used to highlight important information or draw attention to specific content, such as warnings, tips or key points.
Limitations
Only blue callouts are available.
Best practices for using callouts
Use clear and concise language
Keep the text short and to the point. A callout should immediately convey its message, so avoid long paragraphs.
Position for visibility
Place callouts in high-visibility areas, such as at the top of a page, titles or above important content.
Do not overuse it
Too many can dilute their effectiveness and annoy the user. Keep the number of callouts limited to the most important information.
