Why Aren't My Font Awesome 5 Icons Displaying Correctly in CSS?

Font Awesome 5: Troubleshooting CSS Content Issues

Problem:

Users face a recurring issue where Font Awesome icons fail to display correctly in CSS content, showing the icon's code instead.

Explanation:

In Font Awesome 5, there have been significant changes in the CSS integration process, which require careful attention to specific code elements.

How to Fix:

1. Import the CSS File:

   Font Awesome 5 provides both a JavaScript SVG and a CSS integration method. Ensure you are using the CSS integration method. Import the CSS file into your head tag using a link element:

   <link rel="stylesheet" href="https://use.fontawesome.com/releases/v5.13.0/css/all.css">

   Copy after login

   Alternatively, you can import it within your CSS file:

   @import url("https://use.fontawesome.com/releases/v5.13.0/css/all.css")

   Copy after login

2. Correct the Font Family:

   In Font Awesome 5, the font-family should be set to "Font Awesome 5 Free" instead of 'FontAwesome'.

3. Use the Correct content Value:

   For icons, the content property expects a hexadecimal unicode value prefixed with f instead of /f. For example, for the previous icon, you should use:

   content: '\f35a'; /* Note the \f prefix */

   Copy after login
