preloading font with rel preload

Your preload-Tag takes the argument "crossorigin", which must be given for Webfonts, even if they are on the same host as your website.

See https://developer.mozilla.org/en-US/docs/Web/HTML/Preloading_content#Cross-origin_fetches or https://www.smashingmagazine.com/2016/02/preload-what-is-it-good-for/#early-loading-of-fonts .

I kept getting the warning when trying to load preload a google font.

Turns out I was missing the fact that the font was being loaded as a style from google. I solved this by setting the as="style' and then using rel="stylesheet preload prefetch".

See code example below:

<link 
 as="style"
 rel="stylesheet preload prefetch" 
 href="https://fonts.googleapis.com/css2?family=Roboto:wght@300;400;500&display=swap" 
 type="text/css" 
 crossorigin="anonymous" />

Happy coding =)
