To fix custom font issues, verify that the font files are correctly linked in your CSS and ensure that they are served with the proper MIME types. Check browser compatibility for the font formats used.

Using custom fonts can enhance the visual appeal of your web application, but issues can arise that prevent them from displaying correctly. To troubleshoot font problems, start by verifying that the font files are correctly linked in your CSS file. Ensure that the @font-face rule is properly defined, specifying the font-family, source URL, and any necessary font formats (e.g., WOFF, TTF, EOT). Check that the URLs provided in your CSS are correct and accessible, as broken links will prevent the fonts from loading. Ensure that your web server is configured to serve font files with the appropriate MIME types; for instance, WOFF files should be served as font/woff, and TTF files as font/ttf. Additionally, browser compatibility is crucial when using custom fonts; ensure that you include a variety of font formats to support different browsers, especially older versions that may not support newer formats. Testing your application on various devices and browsers can help identify issues that may not be evident in a single environment. Implementing fallback fonts in your CSS can help maintain a consistent appearance even if the custom font fails to load. Regularly checking for updates or changes in font hosting services can also prevent potential issues down the line. By systematically addressing these factors, you can ensure that custom fonts enhance rather than hinder the user experience.
