Question

Web development

Fucking Pagespeed shows a warning

Ensure text remains visible during webfont load

With a link to an article about font-display
I tried everything font-displayand it still shows me this warning. How did you get rid of it?

Answer 1

The guide on the link helps to get additional. points from Google and in general extra. increase website rendering speed. At the same time, this guide is not a panacea for this error, but the speed of the initial display of the site as such only increases from following it.
The appearance of this error in the case of compliance with all recommendations and optimizations is most likely a flaw in the algorithms.
