>CSS uses these to decide how that thing is to be displayed. I already agreed with you: "they should reflect their design function" You seem to be conflating semantic classes with presentational ones: If all your articles have a blue border, maybe it makes sense to have .article have a border property. If your events, articles, and recipes all share the same Card format, it makes better since to keep those styles in .card. >Except they don't, as I already explained. You didn't explain; I said just remove the `highlight` class. >Doesn't mean the standard practice is actually good, or that there's no room for improvement. Not on its own, but the fact that this arose out of the maintenance nightmare that was "semantic CSS" from 5 years ago explains why it is now a best practice.
