Animate caption

Hello everybody,
I have been trying to achieve something,all i wanted to do is add a class to animate (fadeInRight) a simple line of text.
So far i cannot seem to get the caption text to animate and i cannot do it with the normal enfold commands, i cant find anything in the documentation or what i found simply doesnt work maybe becuase of my cache or i don’t know.

All i wanna do is to know if there’s a way to add a class in the text field like
<h4 class=”animate”>random text</h4>
to get the text to simply fadeInRight ?

Thanks for your patience..
