The form input fields should autofocus so they can be typed in immediately when each form step loads. This will allow the form to be navigable completely by keyboard. This can be achieved by adding the autoFocus prop on the input fields.

This should apply to the slider as well.

If, for some reason, the autoFocus attribute doesn't work on the elements, they can be given refs and a useEffect can be used to set the element's focus with ref.current.focus().
