Toast
Components to present information with visual cues.
- To display temporary short messages.
- To react to user input (let users know something is happening).
- If the message should stay on the screen—use an alert.
- When you want to include an action—use an alert.
- When an action is necessary before continuing—use a modal or dialog.

Toasts usually disappear on their own. So any critical messages or errors that would block a user’s flow don’t get enough attention.
For errors and other critical messages, place the message in the screen itself. If the message is important but doesn’t block the flow, use an alert. If the user should be blocked, use a modal or dialog.
Toasts are built for messages only, not actions. They can include links to additional information, but nothing that would be required. Toasts can disappear, meaning the actions would too.
Make the actions available directly on the screen. If there are actions associated with the message, use an alert. Otherwise, use buttons and other action components.
To maximize accessibility, make sure the message is clear from the content. Icons can also support the message.
Color alone doesn't always distinguish different toast types.
Toasts only appear temporarily, so there’s no time for long messages. Limit yourself to no more than 1 line. Aim for shorter if possible.
If more information is necessary, use a text link to a more detailed description (don’t truncate the toast itself).
Success toasts confirm that a user’s action was processed. Use them to show success when the screen doesn’t change.
Warning toasts warn the user about situations that might be unfavorable. Use them for general travel warnings. Don’t use them for any critical information that should break the user’s flow.
Informational toasts present general content without an associated positive (success) or negative (warning) emotion.
This component can be in different positions that are commonly used on websites, such as a corner of the screen. For mobile devices, the component is located at the top of the screen and is stretched to cover the entire screen width.
