How to recognize it

Looks like an ordinary button, but its background or border changes while it is pressed. Often an icon button in a toolbar, such as Bold or Mute.

Each press flips between pressed and not pressed.
The label stays the same; the pressed state is shown by the style and announced through aria-pressed.
Several toggle buttons can be grouped, for example Bold, Italic, and Underline.
