The only syntax you need is with that "X" being filled by any details.

What I covered in the explanation for scroll boxes was two incidents: "What happens if you have too much text?" and "What if I want the text box to be shorter/taller?" Thus I made sure to answer those with essentially "the box, at a certain point, will start using the scroll feature" and "yes, you can appoint a height for the scroll box."

I apologize if those details made you confused that there were much more to scroll boxes than the basic " ." If you have any other questions, just ask. Otherwise, enjoy!
