> You can handle 99% of use cases for specificity just nesting classes. Nesting classes can get really messy and I'm not sure that really makes sense to do in "99% of use cases" if the goal is to make something specific. Mixing classes allows you to apply multiple styles onto a single element which can be really handy but using that as the way to target a specific, single element means you can't re-use some of those classes in the same way otherwise you run the risk of targeting more than one element in the same way. Specificity should usually be handled through the cascade and / or IDs; that's what they were meant to do. Classes provide buckets of styles as do IDs and both can be used in the same way with IDs targeting only a single element and not a compose-able one. Ultimately you can specifically target in CSS a variety of ways. Outright saying one way is just wrong or "[an] ICBM" kinda ignores the use cases of the various ways to do it to attempt to force a single answer where I do not think a single answer is satisfactory.
