Choosing between variations

  • Use the Hint text variation to provide additional information that pertains to the question being asked or all of the options presented.
  • Use the Label header variation when a heading is required within the legend that acts as a label for the radio buttons. This can aid users in navigating the form questions, particularly in the sub-task pattern
  • Use the Description text variation to provide additional details about one or more radio button options. This variation is superseded by the Tile variation.
  • Use the Tile variation to provide additional details about one or more radio button options within a large and well defined tap target.


  • Radio buttons typically appear inside of <fieldset>s. The class name of usa-input-error may be placed on the <fieldset> that contains all of the radio buttons.
  • The error message is placed just below the <legend>.
  • See form error handling for additional guidance.
