* Not a teacher
The only thing that crosses my mind is that "metro" is a shortened form for "metro-sexual". I think that, in your context, "fancy", "stylish" or even "complicated (meaning that the page is too complex, has a lot of elements and it is kind of hard to use)" would be the most appropriate synonyms.
