How can I solve the issue of my custom fonts "jumping" back to the fallback font when launching my Webflow site in Google Chrome? I have already tried using .ttf, .eot, and .woff versions of the font, but it hasn't resolved the problem. Any suggestions?

TL;DR
  • Preload fonts via the Project Settings and ensure correct @font-face declarations with font-display: swap;.
  • Optimize font files, clear browser cache, update Chrome, and check for extension interference.
  • Consider using a font-loading library like Web Font Loader for better performance.

When custom fonts "jump" to a fallback font in Google Chrome, it may indicate a problem with how the fonts are loaded or rendered. Here are steps to troubleshoot and resolve this issue:

1. Check Font Preloading

  • Preload Fonts: Make sure your custom fonts are preloaded. Go to the Project Settings under the Fonts tab, and ensure you've added a preload link (e.g., rel="preload") for your custom font files.

2. Review Font Face Declaration

  • Correct Font Formats: Double-check your CSS @font-face declaration to ensure it correctly references all font formats, and set font-display: swap; to prioritize displaying text.
  • Example Syntax: Use an inline style reference like font-display: swap; in your Webflow project for ensuring better font rendering.

3. Check Rendering Performance

  • Optimize Font Files: Ensure font files are properly optimized. Large files can delay rendering and cause fallback font flashing.
  • Browser Cache: Clear your browser cache to ensure it's not affecting font rendering.

4. Inspect Chrome Settings

  • Chromium Bug: Check if the issue is related to a specific Chromium bug. Ensure you are using the latest version of Chrome by updating your browser.
  • Disable Extensions: Sometimes browser extensions can interfere. Test rendering in Chrome's Incognito Mode to rule out interference.

5. Utilize Font-Loading Libraries

  • Font Loading Libraries: Consider using a JavaScript library like Web Font Loader to improve custom font loading and fix rendering delays.

Summary

Ensure your fonts are preloaded and correctly declared with @font-face using font-display: swap;. Optimize fonts for rendering performance, clear your browser cache, and test for extension interference. Consider using a font-loading library if problems persist.
