How to change font in Full Width Easy slider?

I can’t for the life of me figure out how to do it… why is there not a simple function to do this?

I am designing a website for Wedding cars… a standard font is not ‘classy’ enough.

I’d like to change it to Italics at the very least, but preferably another font as well that is kind of calligraphy style but still legible.

Thanks in advance!
