Accessibility issues with toasts and how to mitigate them
You may have recently read Adrian Roselli’s Scraping Burned Toast, Chris Coyier’s summary of the current “toast conversation”. Or maybe you’ve browsed the GitHub repository for A Standard ‘Toast’ UI Element and its WICG discussion thread.
Or maybe you’re familiar with the concept of toasts from Android development and Material Design.
But regardless of how familiar you are with the concept of a “toast”, work has been progressing on try to pave the existing cow paths different UI library definitions have set for said potential component. Unfortunately, the level of concern given to the accessibility and inclusive UX of a toast component varies quite a bit, depending on which component library you review.
Defining a toast
At a high level, toasts should be used to indicate the completion of a task or process initiated by the user or the application itself. For instance, a notification verifying the saving of a file, that a message had been properly sent, or a that a meeting was about to start.
If someone were to ignore, or miss a toast message, due to its timed display, there should be no negative impact on their current activities or the status that the message conveyed. Using the previous examples, ignoring a toast message would still mean that a file was saved, that a message was sent, or that a meeting was about to start.
Inclusive UX of a toast
A toast component should be considered a type of status message, and thus should be given a
role="status". This will ensure that when a toast is displayed on screen, its contents will be, politely, communicated to assistive technologies, such as screen readers.
Ideally, a toast component should contain no interactive controls, as by doing so an immediate divergence of inclusive UX is introduced.

Material Design as gospel
“We went out with the original Material Design with what was a very fresh and very opinionated style. We wanted to get attention,” says Matias Duarte, the head of the Material Design group at Google. “And it was so strong and so opinionated and so successful, a lot of both the designer and developer community took it as a ‘gospel,’ perhaps is the right word.”
”We spent two years telling people ‘this is how to make Material yours,’” Duarte says, “and it didn’t work.” But he doesn’t blame developers. The problem is that Google didn’t provide the right tools. Specifically, he believes Google’s guidelines didn’t separate out the styling of the button from its function. Google wants apps to work like other Material Design apps, but it never meant for all Android apps to look like each other.
