In the exact example you've given, you probably can. But if you just use .contact__container as your selector, you're relying on DOM ordering to ensure that it overrides the .container rule, which can be fragile in some contexts. By using .container.contact__container you're using a higher specificity selector and guaranteeing that it will override the .container rule.
