LESS mixins

This touches on it some. It has the super easy to follow example of:

1. .hiddenMixin() {
      color: black;
   }
    
2. p {
      .hiddenMixin()
   }
    
3. p {
      color: black;
   }
    

1+2=3 above. Get it? The link I provide also shows off setting variables at parameters like so:

.round-borders (@radius) {
   border-radius: @radius;
