[Events +] I'd like to insert a text above, *your answer*

Hy,

I have another question,
After an answer, Yes - no - Maybe.
I'd like to insert a text above, *your answer*

I wanted to do this with css and: before but it doesn't work.
My html code:
<input class="current wpmudevevents-no-submit" type="submit" name="action_no" value="No" disabled="disabled">

or can I customize it in the template

$content. = apply_filters (' eab-rsvps-button-no',
					"<input class=".
						(($booking_id && $booking_status ==' no')? current wpmudevevents-no-submit':' wpmudevevents-no-submit'. $default_class).
						type= "submit" name= "action_no" value= "'. (' No', Eab_EventsHub:: TEXT_DOMAIN).
					'" '.(($booking_id && $booking_status ==' no')? "disabled=" disabled ":'')." />',
					event->get_id ()
				);

many thanks for the answer
