Does LESS have an “extend” feature?

Question

SASS has a feature called @extend which allows a selector to inherit the properties of another selector, but without copying the properties (like mixins).

Answer 1

Easy way to extend a function in Less framework

.sibling-1 {
    color: red
}
.sibling-2 {
    background-color: #fff;
    .sibling-1();
}

Output

.sibling-1 {
  color: red
}
.sibling-2 {
  background-color: #fff;
  color: red
}
