Stylizing default Preformatted text style?


I'm using Woocommerce and I entered in some text and set it to be "preformated". I'd like to change the style a bit (change the blue backgound etc.). I was wondering if this had to do with the theme (upfront) or woocommerce?

And for which ever one, where could I find that particular CSS to change?

EDIT: I checked the upfront editor typography settings and the Preformatted Type Element didn't seem to match what's displaying in woocommerce product page (at least not blue highlight). See the second screenshot.
