The use of web fonts can cause cumulative layout shifts (CLS), which negatively impact user experience. To minimize CLS, it's recommended to avoid using web fonts or use built-in fonts instead. If web fonts are necessary, consider using fewer font files, variable-size fonts, hosting your own fonts, and the `font-display` property with a fine-tuned fallback font. The `font-display` property can be set to various values, including `swap`, which ensures that the user sees a visible fallback font while the correct font is loading, or `fallback`, which hides the text for 100ms before showing the fallback font. Using performance monitoring tools like Sentry can help track CLS scores in production and identify areas for improvement.
