@extend Directive

The fourth helpful feature allows us to apply preset CSS properties from one element to another, creating a relationship between selectors. This means that one selector can inherit the properties of another selector.

The html code is:

Let's see how we can inherit styles with the help of sass.

The .submit-button selector inherits all of the styles from the .send-button selector using the @extend directive.
