Why Are My Font Awesome Icons Showing as Empty Squares?

Troubleshooting Font Awesome Icon Display Issues

Encountering empty squares instead of desired Font Awesome icons can be frustrating. Let's explore a common issue and its solution.

The problem often arises when trying to include Font Awesome icons on a web page. The code provided correctly includes the necessary style sheets, including the version-specific file for Internet Explorer 7. However, the actual icon declaration is missing a crucial element.

To display Font Awesome icons correctly, two class names must be used: the fa class and the class that specifies the desired icon. For example, to display the Twitter icon, the code should be:

<i class="fa fa-twitter"></i>

In the example provided, the fa class is missing, resulting in the square placeholders.

Bootstrap 5 Update

With the release of Bootstrap 5, the fa prefix has been deprecated. The default icon style is now "fas" for solid icons, and "fab" for brand icons. Therefore, the code should be updated to:

<i class="fas fa-twitter"></i>

Ensure that both the fa and icon-specific classes are included to display Font Awesome icons correctly.
