Button is a graphical control element that gives users a simple way to trigger an event, like search queries on a search engine or interacting with dialog boxes (for example, confirming an action).

The control appears as a recognizable, clickable element, similar to a physical button. It is typically placed throughout our UI, in places like panels or overlays.


  1. Container: The background of the Button. It includes a background color, stroke width and style, radius, and elevation properties.
  2. Content: Icon and/or label.

The Button supports the following configurations:

anatomy configurations


anatomy types
Button typesAbout
Primary buttonUsed for actions with the most emphasis when a clear "call to action" is needed on a screen, or when from a range of commands one is predominantly used.
Secondary buttonUsed for actions with less emphasis. These are the most commonly used buttons as they are visually clickable but do not distract from the content.
Tertiary buttonUsed for actions with the least emphasis.
Floating buttonUsed for actions that can hover over the content.
Destruction buttonUsed for actions with a negative emphasis that results in data loss.
Acceptance buttonUsed for actions with a positive emphasis that results in success.
Toggle buttonUsed for actions that allow users to switch between two or more states or options.


The Button supports multiple states to indicate its status:

NormalThe default state of the Button.
DisabledA state when the Button is not active for connection or input reasons.
PressedA state when a user taps on the Button. The Button animates (dims and shrinks) to provide feedback.
ActivatedA state when an action is activated. Most commonly used in the toggle Button to switch between normal and activate/selected states.
BadgeA state that indicates a status, notification or event. The Button shows a small UI item called a badge on top of the icon.
