> Do you think the separation of content from appearance is a bad idea, or that HTML/CSS doesn't do it well, or something else?
Several things:
1) To a first approximation, I think the separation of content from appearance is a fine idea.
2) Which is to say, to a second approximation, I think it's terrible: I have an inchoate intuition that content vs appearance is a bad paradigm because it is an attempt to shoehorn a triad into a false dichotomy, and the real correct solution is separation of content vs appearance vs a third thing, maybe "functionality".
3) But that aside, and for the moment CSS aside as well, HTML's separation of content and appearance is catastrophically bad. It is predicated on fundamentally mistaken ideas as to what is content and what is not.
I have one particular favorite hobby horse example of this, which really captures how apparently trivial errors can have far-reaching consequences.
