Notes on Implementation
We do not recommend the use of Bootstrap’s Toast component, but instead suggest to use Dismissible Alerts. Dismissible Alerts provide the same function as the Toast component, but are not timed which allows users an adequate amount of time to view the message without it being timed-out.
If a toast is preferred over a dismissable alert, the documentation for Bootstrap Toasts can be consulted for further accessibility information. Toasts are non-actionable notifications designed to mimic push notifications used by desktop and mobile operating systems. The default time-out of toasts may not be suitable for users of assistive technology, who may not not have time to view the message before the time-out. Dismissable alerts allow for users to dismiss the message after viewing to ensure any relevant information is viewed.
