"Ensure text remain visible during webfont load"

Hi everyone,

when I test my website speed using Google PageSpeed Insights I get this message: “Ensure text remain visible during webfont load”. How can I solve this in order to get a better score?

Thanks.

This maybe useful?

I followed the tutorial but I get the same message regarding this URLs…

/fonts/et-line.woff
/fonts/fontawesome-webfont.woff2?v=4.7.0

add font-display: swap; to your font stylesheet
