XSLT performs transformations (i.e., takes input and produces output). This sounds to me like a "program" so I wouldn't be surprised that a language like XSLT might be Turing complete.
HTML and CSS are much more "static" in flavor (hence the OP's use of the term "descriptive") and so it might be more unexpected that they can perform universal computation.
