Is it possible for a CSS class to acquire the properties of one or several other classes?

Yes, it is possible for a CSS class to acquire the properties of one or several other classes using the CSS inheritance property. The inheritance property allows child elements to inherit the styles of their parent elements. To achieve this, the child element must have a class that references the parent class using the "extends" keyword. For example:

.parent {
  color: red;
}

.child {
  extends: .parent;
  font-size: 16px;
}

In the above example, the .child class will inherit the color property from the .parent class and also have its own font-size property.
