# Snackbar - Accessibility

A Snackbar shows brief user feedback messages that overlay content, with an optional action such as Undo.

## General

From an accessibility perspective the snackbar component is problematic.

* Since the popovers disappear on their own users might not even see them, especially when zoomed in.
* The popovers are in practice impossible to reach with keyboard since they appear away from the element that triggered them.
* Important elements on the page might get hidden behind the popover.

A snackbar must never be the backbone of your user experience, it should only ever include information and actions that are available elsewhere.

* Keep messages and actions short since the popover is visible only for a short time.
* Ensure any information and action in the snackbar, such as Undo, is possible to do elsewhere.
