Animate letterspacing on scroll in to view

Is it possible to have the letter spacing attribute animation when the element scrolls in to view?

I’m at a loss on how I can achieve this.

Any help is much appreciated.

Hi Ch0nz,

did you get any help or resolve the issue by yourself? I am trying to achieve the same for a client.
Would be great if you could share your thoughts.

Kind regards, peter
