Unicode for Font Awesome 5 Star Icons: Using the 'far' and 'fas' Classes

Font Awesome 5 offers both regular and solid star icons, represented by the Unicode values '\f005' for both. To utilize these variations in your rating system, you can leverage CSS to toggle between the 'far' and 'fas' classes.

The 'fas' class represents the solid star, while 'far' represents the regular star. The key to switching between them lies in adjusting the font weight. By setting the font weight to 900 for the checked star and 200 for the unchecked star, you can effortlessly switch between the solid and regular versions, respectively.

Here's an updated code snippet that takes this into account:

input.star:checked ~ label.star:before {
  content: '\f005';
  color: #e74c3c;
  transition: all .25s;
  font-family: 'Font Awesome 5 Free';
  font-weight: 900;
}

label.star:before {
  content: '\f005';
  font-family: 'Font Awesome 5 Free';
  font-weight: 200;
}

This code ensures that the star icon is regular when unchecked and solid when checked, allowing you to create a dynamic and interactive rating system with ease.
