Keyboard and Focus

  • The trigger of Button is the same as the native button, when the button is focused, it can be activated by Enter or Space key
  • The buttons in the ButtonGroup are managed in the same way as the focus of a single button, and can be switched by Tab and Shift + Tab

Content Guidelines

  • Buttons need to be clear and predictable, users should be able to predict what will happen when they click the button
  • Buttons should always start with a strong verb that encourages action
  • To give the user enough context, use {verb}+{noun} content formulas on buttons; in addition to common actions like "Done", "Close", "Cancel" or "OK"
