What is the proper CSS class to change the default Widget

What is the proper CSS class to change the default Widget font while inside the upfront editor?

Situation: I changed pretty much all styles that use the ‘Special Elite’ font in the panino theme to use Google fonts ‘Original Surfer'

However when I enter the upfront editor the widget text displays as 'Special Elite'.

When I exit the editor it displays as 'Original Surfer'. It's just a little confusing for standard user.

What CSS would I have to enter for the font to display as 'Original Surfer' while in the upfront editor mode?
