How Can I Use Font Awesome Icons in CSS Content?

Using Font Awesome Icons in CSS Content

In an attempt to utilize Font Awesome icons within the content attribute of CSS, you may have encountered difficulties due to the inability to embed HTML code within that context.

Font Awesome 5 and Later

For Font Awesome 5 and later, you should proceed as follows:

• Define the font family, ensuring you specify either "Font Awesome 5 Free" or "Font Awesome 5 Brands" depending on your desired icon type.
• Include the content property, but use the corresponding Unicode escape sequence instead of HTML entities.
• Set the font weight to 900.

a:before {
   font-family: "Font Awesome 5 Free";
   content: "\f095";
   display: inline-block;
   padding-right: 3px;
   vertical-align: middle;
   font-weight: 900;
}

Font Awesome 4 and Earlier

For Font Awesome 4 and earlier versions, adopt these steps:

• Locate the font awesome style sheet.
• Identify the class of the intended icon (e.g., fa-phone).
• Copy the content property associated with that class, which contains the entity code.
• Utilize this code within your CSS, assigning it to the content attribute.

a:before {
    font-family: FontAwesome;
    content: "\f095";
}

Spacing Adjustments

If you require spacing between the icon and text, fine-tune the following settings:

• Set the display property to inline-block.
• In the a:before selector, specify a suitable padding-right value.

a:before {
    font-family: FontAwesome;
    content: "\f095";
    display: inline-block;
    padding-right: 3px;
    vertical-align: middle;
}

Hover Effects

To modify the icon on hover, add a separate selector for :hover and specify the updated Unicode escape sequence within its content attribute:

a:hover:before {
    content: "\f099";
}

Width Adjustments

To avoid icon movement due to size variations, consider setting a fixed width in the base declaration:

a:before {
    /* Other properties here, as seen in previous code snippets */
    width: 12px; /* Set a desired width to prevent icon shifting */
}
