I tried installing a custom font on my WordPress site by editing the theme’s CSS file, but the font doesn’t display correctly on some browsers. I uploaded the font files to my server and linked them, but it’s still inconsistent. What’s wrong?

Custom fonts not displaying consistently across browsers can be caused by incorrect font formats or linking methods. Ensure your font files are in multiple formats like .woff, .woff2, .ttf, and .eot to maximize compatibility. Some browsers, especially older versions, only support specific formats.

Check your CSS syntax for linking the fonts. A common structure looks like this:

@font-face {
    font-family: 'MyCustomFont';
    src: url('fonts/mycustomfont.woff2') format('woff2'),
         url('fonts/mycustomfont.woff') format('woff');
    font-weight: normal;
    font-style: normal;
}

Ensure the paths to the font files are correct relative to your theme’s directory. Use absolute paths if necessary to avoid issues with file locations.

Another issue could be caching. Clear your browser and site cache to ensure the latest files are being loaded. Also, check your server’s MIME types configuration. Fonts may fail to load if the server doesn’t recognize their types. Add this to your .htaccess file if needed:

AddType application/font-woff .woff
AddType application/font-woff2 .woff2

Finally, test your site on different devices and networks to confirm the problem isn’t local. If the issue persists, consider hosting your fonts on a reliable CDN or using a web font service like Google Fonts for better performance and compatibility.
