Hello!
I want to try and implement a CSS property, font-display: swap. The reason is that on page speed insights my largest contntful paint is 5.3 seconds on mobile, and 4.65 of those are Render Delay. The largest contentful paint on my start page is an H1 headline. According to my own research, this property could change things so that a default system font is loaded first, and then swapped when my chosen is loaded (Dosis and Josefin Sans).
My question: Where in Cornerstone (or wherever) can I enter the CSS property font-display: swap so that it affects the entire page?
