Extending with Compound Selector in SASS

The use of the @extend directive is not limited to class selectors. In principle, any selector can be extended, even single elements. Let's look at an example:

Let's look at an example:

style.scss.active-link {
  @extend a:active;
}
  
a:active {
  color: blue;
}

As a result of compilation we will see that .active-link inherits the color property from a:active:

style.cssa:active, .active-link {
  color: blue;
}

styles.scssbutton {
  @extend .box:hover;
}
  
.box:hover {
  color: #14147e;
}

styles.scssbutton:active {
  @extend input:focus;
}

button:blur {
  @extend input:blur;
}

input:focus {
  color: #14147e;
  border-color: #b5b5d1;
}

input:blur {
  color: #040433;
  background-color: #87878f;
}
