"Scaling class selectors" is a false problem: actually, classes and pseudo-classes "increase the granularity of control over elements" (which are much closer analogues of classes in the OOP sense than CSS classes) better than in 1997 because useful new selectors and pseudoclasses have accumulated over the years. Class selectors (and everything else) become weak, as should be expected, with monkeys ("With mutually exclusive classes like Big and Small, it is possible for elements to apply both classes at once") working with no actual design ("parameterise Card to take a size option which is either Big Medium or Small, a rounded boolean, and an align option which is either Left, Right, or Center").
