Bottom app bars display navigation and key actions at the bottom of mobile and tablet screens.

Icons inside buttons

Decorative images inside a button also containing visible text are never read to the screen reader.

For example, when a screenreader encounters a “Send message” button with a decorative paper airplane, the icon must be ignored.


Do not rely on an image’s alternative accessibility text label to name an icon button. Directly encode the name into the button component itself. The icon should be ignored by the screen reader.
