Correct answer: Using more than two custom fonts can cause fonts to flicker on loading, showing a flash of unstyled text. This is a poor user experience and increases the CLS score. Instead, the designer should try to find comparable Google fonts to use..
Why this is the answer
Using multiple custom fonts can trigger a flash of unstyled text (FOUT) or layout shifts during loading, increasing Cumulative Layout Shift (CLS). This negatively affects visual stability and user experience, which are part of Page Experience signals. Proposing comparable Google fonts reduces load time and ensures predictable rendering. Optimizing font usage maintains both performance and SEO metrics.
