Update:
I asked Typography.com about this;
My email:
Hello, does Webflow work well with cloud.typography? They do not actively support it but I imagine others might have asked about this. I wish to sign up for both cloud and web flow, but would like to be sure both can be used together well without too much hassle.
Their reply:
Hi Yaco,
Thanks for getting in touch about using webfonts! Cloud.typography can be used across any site that allows you to edit the HTML. That said, it does appear that Webflow requires fonts to be embedded in a way that Cloud.typography cannot support, so it looks like using Cloud.typography webfonts may not be possible.
Feel free to let me know if you have any questions!
Kind Regards,
