How Do I Correctly Use Font Awesome 5 Font-Families with Pseudo-Elements?

Using Font Awesome 5 Pseudo-Elements with the Correct Font-Family

When adding icons to a web page using CSS pseudo-elements with Font Awesome 5, the specific font-family selection can be confusing. There are four primary font-family options: Font Awesome 5 Free, Font Awesome 5 Solid, Font Awesome 5 Brands, and Font Awesome 5 Regular.

Case 1: Brands Icon (Using "Brands" Font-Family)

For brand-specific icons, such as the Twitter icon, the correct font-family is "Font Awesome 5 Brands."

Case 2: Solid Icon (Mistakenly Using "Solid" Font-Family)

For solid icons, do not use the "Font Awesome 5 Solid" font-family. Instead, use "Font Awesome 5 Free." "Font Awesome 5 Solid" only affects the icon's weight, not its font-family.

Using Multiple Font-Families

To ensure the browser finds the correct icon, include all four font-families in a single property like this:

font-family: "Font Awesome 5 Brands","Font Awesome 5 Free","Font Awesome 5 Regular","Font Awesome 5 Solid";

The browser will prioritize the fonts in the order they appear. If an icon is not displayed, it may not be included in the free version or may require a PRO subscription.

Additional Notes

• "Regular" and "Solid" fonts only differ in weight, not font-family.
• Some Regular icons are available only in the PRO package.
• Light and Duotone icons are also part of the PRO package.

By following these guidelines, developers can ensure that Font Awesome 5 icons are consistently displayed using the correct font-family.
