Using font in "Drag and Drop" website templates

You'll have to ask Wix if they support hosted fonts from 3rd party sites like Adobe & Google fonts. 

Ideally you should be able to add embedded <code> inside the <head> tag of your site Template or Theme.  If Wix doesn't allow embedded font code, or is not integrated to work with AdobeFont projects,  find another site builder.
