I'm personally not a fan, but still am hesitating to point out that Scheme was, in fact, chosen as the language for styling and transforming SGML (DSSSL, still available as OpenJade), and I believe also Brendan Eich's first choice, presumably because of the DSSSL precedent. But then supposedly his bosses told him it has to be more like Java, at least in name.
I'm not a big believer in syntax (and think LISPy language will always remain niche, which is part of its appeal), but one thing I'd imagine is that LISP/Scheme could've helped to prevent the syntax excess that is CSS, simply because there were already plausible styling examples for eg. classic stateful recto/verso print formatting, and LISP's homoiconicity would've make CSS syntax look kindof gross.
