In "programmatic" code, declaring two classes with the same name in the same namespace is generally either some sort of syntax error or one will "shadow" the other; it doesn't just silently merge the behavior of both classes. |

The CSS version is a risk, for sure. The dev tools in all the main browsers will tell you where the extension happens and show yiu the order the complecting rules are applied, so it’s fairly easy to debug. Bugs/misbehaving code is usually a problem of structure. In other languages, we take on the need to apply structure; just do the same with CSS.
The mechanism that allows this merging behavior is the means by which intentional reuse is composed. It allows yiu to set general and specific rules sets. This seems conceptually similar to OO classes and subclasses, to me.
