Best Practices
Properties
Variant
| Variant | Usage | Example |
|---|---|---|
info | Message without a clear semantic that doesn’t require immediate attention. | “There are 5 new transactions” with a View new transactions action, when in a page with outdated content |
critical | Action that failed due to a technical error or a user error. Include a proposed action or, when it’s not possible, explain what to do next. | ”The font could not be deleted because it’s used in styles. Please remove it from styles and try again.” with a View styles action |
warning | Unexpected behavior or something to be cautious about. Consider including a proposed action or explaining what to do next. | “The product was saved with 5 issues” and a Fix issues action |
positive | Action that matched or surpassed expectations. If the action takes a while to process, use a positive Toast for the submission itself and an info Alert to indicate progress. | “Product successfully created” |
Icon
Each Alert variant includes a specific semantic icon that should not be customized.
Message
- Write a brief and direct sentence with 240 characters at most. Prefer to include an action that complements the message when needed.
- Don’t use technical language. For example, use ”The invoice could not be sent because of a technical issue” instead of ”Error 298dx9283 prevented the invoice from being sent”.
- Use sentence case, but capitalize proper nouns.
- Don’t use personal pronouns.
Action
Keep the message brief by including an action that complements it, such as to:
- Provide more details in a modal or related page.
- Retry a failed action.
- Undo a successful action.
- Focus on the first error in a form with issues.
- Refresh outdated information on the page.
Read the Button documentation for more details.
Dismissible
Toasts are always dismissible. For non-dismissible notifications, read the Alert documentation.
Position
- Position in a container: Considering left-to-right interfaces, Toasts pop from the bottom of the screen and rest on the lower right-hand corner. This is the default behavior and it should not be customized.
- Multiple toasts: Avoid displaying more than one Toast at the same time. Prefer to summarize the result of an action in a single Toast. For example, use ”34 products successfully saved”.
Behavior
Timing
- Trigger: Toasts appear immediately after an action is triggered (user presses Save) or the loading feedback is over (Button stops spinning).
- Duration: Most Toasts should last between 5 and 10 seconds, following an average of 175 milliseconds per character. Use a permanent toast only when they require attention, such as critical Toasts, warning Toasts, and any Toast that is not the immediate result of an user action.
