Toasts
Push notifications to your visitors with a toast, a lightweight and easily customizable alert message.
Examples
Basic
To encourage extensible and predictable toasts, we recommend a header and body. Toast headers use display: flex, allowing easy alignment of content thanks to our margin
and flexbox utilities.
Translucent
Stacking
When you have multiple toasts, we default to vertically stacking them in a readable manner.
Placement
Place toasts with custom CSS as you need them. The top right is often used for notifications, as is the top middle. If you’re only ever going to show one toast at a time, put the positioning styles right on the
.toast.
For systems that generate more notifications, consider using a wrapping element so they can easily stack.
You can also get fancy with flexbox utilities to align toasts horizontally and/or vertically.
Accessibility
Toasts are intended to be small interruptions to your visitors or users, so to help those with screen readers and similar assistive technologies, you should wrap your toasts in an
aria-live region. Changes to live regions (such as injecting/updating a toast component) are automatically announced by
screen readers without needing to move the user’s focus or otherwise interrupt the user. Additionally, include aria-atomic="true" to ensure that the entire toast is always
announced as a single (atomic) unit, rather than announcing what was changed (which could lead to problems if you only update part of the toast’s content, or if displaying the same toast content at a later point
in time). If the information needed is important for the process, e.g. for a list of errors in a form, then use the alert component instead of toast.
