How Does \"?#iefix\" Fix Web Font Loading Issues in IE6-IE8?

Understanding the IE6-IE8 Web Font Loading Fix with ?#iefix

When attempting to load web fonts in older versions of Internet Explorer (IE6-IE8), you may encounter issues. One common solution involves appending "?#iefix" to the URL of the Embedded OpenType (EOT) font file.

How does ?#iefix work?

The solution works by exploiting a bug in the src attribute parser of IE8 and older versions. When multiple font formats are included in the src attribute, IE fails to load any and reports a 404 error.

By adding the "?#iefix" string, the URL is modified to appear like a query string. This tricks IE into ignoring the additional font formats and loading only the EOT file.

Implications for Other Browsers

Other browsers that adhere to the CSS specification will continue to behave as expected and load the appropriate font type based on their support.

Other Considerations

The "?#iefix" solution is a workaround for a specific bug in IE. It is not a recommended solution for modern browsers. For a more comprehensive approach to cross-browser font loading, refer to resources such as Paul Irish's "Bulletproof @font-face syntax."
