Many thanks for your reply.
I’m still on local host with this project, but the more I look into it the more I think I’ll leave it as is because it works fine on mobile phones and increasing this font size for desktop will make those fonts too big on mobiles.
It’s exactly the same as your demo, when you look on those Featured sections at homepage.
Works fine on mobile and all caps on desktop but when you use normal fonts it just makes them too small.
I’ll maybe revert to upper case fonts as in your demo.
