| description | When something goes wrong, the user must be able to recover or try again. Toasts, inline errors, banners, and notification patterns each have a specific role. Use when designing error states, success confirmations, async feedback, in-place editing, or any system that communicates state changes to the user. |

Notifications and Recovery
When something changes — success, failure, or anything in between — the user must know. And when something goes wrong, they must always have a path forward. A notification without a recovery action is just an apology.
Pattern Selection
| Pattern | When to use | Dismissal |
|---|
| Toast | Transient result of a user action (saved, sent, deleted) | Auto-dismiss 4–6s, manual close |
| Inline error | Field-level validation, form errors | Clears on correction |
| Alert banner | Persistent issue affecting the current context | Manual dismiss or resolved state |
| Modal / dialog | Blocking error requiring a decision before continuing | User action required |
| Empty state | No data yet — guide the user to the first action | N/A |
| Skeleton / loading | Async content pending | Replaced by content |
| In-place confirmation | Inline edit saved, row updated, item toggled | Auto-clears after 2–3s |
Toast Notifications
Toasts confirm that a background action completed. They appear without interrupting the user's flow.
Placement: bottom-center or bottom-right. Never top-center — it competes with page content and navigation.
Duration: 4–6 seconds for information. Errors should persist until dismissed — the user needs time to read and act.
Anatomy:
[Icon] Message text [Action] [×]
- Icon: colour-coded (green ✓ success, red ✗ error, orange ⚠ warning, blue ℹ info)
- Message: one sentence, plain language
- Action (optional): "Undo", "Retry", "View" — one action maximum
- Close button: always present on errors; optional on success
✓ "Changes saved."
✓ "Message sent. [Undo]"
✗ "Could not save. Check your connection. [Retry]" ← persists until dismissed
Never: multiple simultaneous toasts. Queue them; show one at a time.
Inline Errors
Inline errors appear adjacent to the element that caused them. They are the most contextual and actionable form of error feedback.
Form validation:
- Validate on blur (leaving a field), not on every keystroke — keystroke validation is noisy
- Validate on submit for the complete form
- Show the error message directly below the field, in red, with an icon
- The field border changes to
--color-error
- Error message is associated via
aria-describedby for screen readers
<label for="email">Email</label>
<input id="email" aria-describedby="email-error" aria-invalid="true">
<p id="email-error" role="alert">Enter a valid email address.</p>
In-place editing:
- When a field is edited inline (table cell, card title), show save/cancel controls adjacent to the field
- On save: brief success indicator ("✓ Saved") that fades after 2s — do not navigate away
- On error: inline error message below the field with a retry option
- On cancel: restore the original value immediately
Alert Banners
Banners are persistent — they stay until the condition is resolved or the user dismisses them.
Use for:
- Service degradation ("Some features are temporarily unavailable")
- Account issues requiring action ("Your subscription expires in 3 days. [Renew]")
- Ongoing sync errors ("Changes are not saving. [Retry]")
- Important announcements tied to the current page
Placement: top of the affected section, not the entire page unless the issue is truly global.
Anatomy:
[Icon] [Message — describes the issue and its scope] [Action] [×]
- One banner at a time per region — multiple simultaneous banners create alarm fatigue
- Dismissible unless the condition is blocking
- Colour follows status colour conventions: red (error), orange (warning), blue (info), green (success/resolved)
Recovery Patterns
Every error state must have a path forward. Design the recovery action at the same time as the error message.
Retry
For transient failures (network, timeout, rate limit):
"Could not load results."
[Try again]
- Retry button triggers the same action
- After 3 failed retries, escalate: "Still having trouble? [Contact support]"
- Show a spinner during retry — do not let the user click multiple times
Undo
For destructive or irreversible actions (delete, archive, send):
"Message sent. [Undo] ×"
- Undo window: 5–10 seconds. Toast persists for this duration.
- After the window closes, the action is final
- Undo is preferable to confirmation dialogs for low-stakes actions — it is faster and less disruptive
Autosave and Draft Recovery
For long-form inputs (forms, documents, editors):
- Autosave every 30–60 seconds silently
- On save failure: "Autosave failed — your changes are stored locally. [Retry save]"
- On return after crash or close: "You have unsaved changes from [time]. [Restore] [Discard]"
Graceful Degradation
When a feature fails but the rest of the product still works:
- Show an error state for the failed section only — do not blank the entire page
- Offer a fallback: "Could not load recommendations. [Browse all products →]"
- Log the error silently; surface only what the user needs to know
Loading and Skeleton States
Loading is not an error, but it is a state that needs design.
- Skeleton screens for content-heavy pages — show the layout shape while data loads
- Spinners for targeted async actions (button loading, inline refresh)
- Progress bars for long operations with known duration (file upload, multi-step processing)
- Never show a blank screen while loading — always show something
Skeleton screens reduce perceived wait time compared to spinners. Match the skeleton shape to the actual content layout.
The Notification Center
Toasts and banners are transient; a notification center is the persistent place a user goes to review and control what reaches them. Two things make it work.
Easy to reach, and easy to control. The user must get to their notification preferences with almost no digging (a bell icon → the center → settings). And keep the control model coarse — 1 to 3 categories at most, each with a simple level:
Off (0) — none of this category
Minimal — only the important ones
All / granular — everything
Don't build a wall of per-event toggles. Two real needs dominate: silence everything, or keep one or two categories. Design straight for those — a prominent "mute all" / "mark all read" plus 1–3 category switches.
Minimise reading. The center is scanned, not read. Group by category, lead each item with a recognisable icon and the entity/action (not a paragraph), show unread state clearly, and let the whole list be cleared in one action. Reading is time (see [[ui-density]]) — a notification center that demands careful reading defeats its purpose.
Notification Accessibility
- Errors use
role="alert" — announced immediately by screen readers
- Status updates use
role="status" — announced politely (after current speech)
- Toasts must be reachable by keyboard — do not use
pointer-events: none on the close button
- Auto-dismissing toasts must have sufficient duration (
prefers-reduced-motion users may need more time to read)
<div role="alert">Could not save. Check your connection.</div>
<div role="status" aria-live="polite">Changes saved.</div>
