Best Practices
Clarity
- Use clear, concise language
- Include actionable information when relevant
- Avoid technical jargon for user-facing alerts
- Tell users what happened AND what to do next
Accessibility
- Use role="alert" for important messages
- Ensure 4.5:1 color contrast ratio
- Don't rely solely on color to convey meaning
- Make close buttons keyboard accessible
Placement
- Position alerts near the relevant content
- Use consistent positioning across your app
- Toast notifications work best in corners
- Inline alerts should appear within context
Timing
- Show alerts immediately after the trigger action
- Auto-close success messages after 3-5 seconds
- Keep error messages visible until dismissed
- Add progress bar for auto-closing alerts
