Implementing Fittext to allow text to fill a div

Hi everyone,
I am attempting to use FitText to create responsive headlines that fill the width of their container. Has anyone successfully implemented or could offer some advice of how to? Any help would be greatly appreciated.

Hey! Were you able to figure this out? I’m looking to do the same thing.

I know I’m super late to the party, and I’m not an expert. But I just set my text to 10VW and 100% height and it was close to what you are looking to do. I wanted my text to almost stick to the constraints of the section. It’s doing just that and I’m not having to make any adjustments at different scales. Might be worth a look?
