Why Aren\'t My Font Awesome Icons Displaying Correctly?

Font Awesome Icons Not Displaying Properly

Many developers encounter an issue where Font Awesome icons render as square boxes instead of the intended icon. Understanding the root cause of this problem is crucial for resolving it effectively.

Incorrect Class Usage

The most common reason for square icons is incorrect usage of Font Awesome classes. By default, two classes are required for each icon: the fa class and the class that specifies the desired icon (e.g., fa-twitter, fa-search).

Example of Wrong Usage:

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

Example of Correct Usage:

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

In the incorrect example, only the icon-specific class is used, while the fa class is missing.

Bootstrap 5 Update

In Bootstrap 5, the fa prefix has been deprecated. The default style is now fas for solid icons and fab for brand icons.

Correct Usage in Bootstrap 5:

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