Moving Text / Buttons that go beyond mobile display size to next line?

Hi,
Can the Button at the bottom "Please Click here to Confirm Appointment" (while text is quite long - when it doesn't fit can it be extended to two lines so that it fits the width of the page? - on mobile devices only) - http://postimg.org/image/jmrmsapzx/
