How to Use Font Awesome Icons as CSS Content?

Use Font Awesome Icons as CSS Content

In using Font Awesome icons as CSS content, avoid embedding HTML code directly within the content property. Instead, follow these steps:

FontAwesome 5:

1. Define the font family as "Font Awesome 5 Free" or "Font Awesome 5 Brands" depending on the icon type.
2. Use the Unicode escape code instead of HTML entities for the icon, e.g., "f095" for "fa-phone".
3. Ensure the font weight is set to 900.

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

FontAwesome 4 and Below:

1. Copy the content property with the corresponding entity from the Font Awesome style sheet.
2. Use the copied content within the content property with the correct font family.

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

For spacing between the icon and text:

1. Set display: inline-block; for the icon to prevent overlap.
2. Add padding-right: to provide space between the two.

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

To change the icon on hover:

1. Create a separate selector for the :hover state.
2. Modify the content property to specify the new Unicode escape code for the hover icon.

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

Consider setting a fixed width on the base icon declaration to prevent nudging due to different icon sizes.
