Can I add a custom font onto the Index Page description? York Template

Hi there,

I have being using an uploaded font through css on most of my headings for my page (all except for the home page). I am using the York Template (as you can see on the template page its that main font on the home page). I believe I'm running squarespace 7.0 still, any code to make that text on the home page a custom font? 
 

Thanks!
