Buttons communicate the action that will occur when the user touches them.
Material buttons trigger an ink reaction on press. They may display text, imagery, or both. Flat buttons and raised buttons are the most commonly used types. There are three standard types of buttons:
Floating action button: A circular material button that lifts and displays an ink reaction on press.
Raised button: A typically rectangular material button that lifts and displays ink reactions on press.
Unelevated button: A button made of ink that displays ink reactions on press but does not lift.
