Why Font Awesome 5 Pseudo Elements Display Squares Instead of Icons

When attempting to modify the content of a span using Font Awesome icons via CSS, you may encounter instances where square placeholders appear instead of the intended icons. This issue arises specifically with pseudo elements.

To resolve this, follow these steps:

1. Ensure the correct Font Awesome version is imported.

<link rel="stylesheet" href="https://use.fontawesome.com/releases/v5.x.y/css/all.css">

2. Specify font-weight: 900 within the pseudo element's CSS. This is required for proper icon display.

.myClass::after {
  font-family: 'Font Awesome 5 Free';
  content: "\f008";
  font-weight: 900;
}

Additional Considerations:

This issue only occurs with certain Unicode code points (e.g., f007 may work while f008 does not).

If you prefer to load Font Awesome using the JS SVG method, refer to the documentation for specific alternative steps.
