Hi there,
The font-display value actually needs to be set inside the @font-face block of CSS: https://developer.mozilla.org/en-US/docs/Web/CSS/@font-face/font-display#Examples
When using Google Fonts,
Google actually provides @font-face blocks of code, so they would have to implement it on their side of things.
Let me know if you need more info 🙂
Does this mean I should add to SIMPLE CSS the following: ( I use Ariel font with GP premium)
