Call to Action–force line breaks

In my Aaron theme, I am using the call to action with a randominzed image in my header. There is three lines of text in my call to action. On some pages, the lines of text show up on individual lines within the call to action, like I want. When other images show up, the lines of text don’t break the way I want. The call to action box seems to size differently depending on which header image I use. Is there any way to control the line breaks within the call to action. For example,
instead of
ipsem lorem ipsem lorem. ipsem
lorem. ipsem lorem ipsem lorem
ipsem.

Could I force

ipsem lorem ipsem lorem.
ipsem lorem.
ipsem lorem ipsem lorem ipsem.
