I read your post. You clearly brought in turing completeness to try and support your argument. Your other points I've addressed, think we're done here.
But I very clearly did not conflate turing completeness as a requirement of a programming language. I just thought it was worth mentioning that CSS3 + HTML5 is Turing complete.
And you are still completely incorrect about CSS being a programming language. I think we are done here.
You misunderstood my (granted) flippant point which was meant to mean 'lookup "programming language" on wikipedia', not 'go to the CSS page and look for it to explicitly call it a programming language'.
The whole point is, nothing about CSS being a stylesheet or presentational language makes it fall outside of the definition of programming language.
A programming language doesn't need to be turing complete. But CSS is neither of the two.
