Thnak you bro, I was having trouble adding my custom fonts, it was because at the end of the src line i was typing "format('ttf')", and well, basically it was causing trouble.
What if i downloaded multiple fonts, like bold, black, light, meduim, regular. Do i have to make different font-face for every font, or doing only changing font weight works?
Accessing public files should not be done as ../public/Ultra-Regular.ttf but rather just /Ultra-Regular.ttf. The public folder points to root in production.
