The purpose of %icon is to provide a standardized set of styles for displaying icons across the project.
Inside %icon, the icon mixin is included. This mixin generates styles for displaying icons, such as setting the font family, font size, and color.
By extending %icon in other selectors, you can easily apply these common icon styles to different elements throughout your project.
In summary, %icon serves as a convenient way to define and reuse styles for displaying icons in your project. It encapsulates common icon styles, making it easier to maintain consistency and make global changes to icon appearances.
Example
<divclass="icon square pd-2"><iclass="fas fa-heart"></i></div><divclass="icon circle pd-2"><iclass="fas fa-star"></i></div>
