This question challenges you to consider how Python handles decorators.

A decorator feature in Python wraps in a function, appends several functionalities to existing code, and then returns it. 

@property decorator is a built-in decorator in Python that helps define the properties effortlessly without manually calling the inbuilt function property().

    def domain(self):
        return self._domain
    
    @domain.setter
    def domain(self, value):
        self._domain = value

# Example usage
obj = Website()
obj.domain = "example.com"
