A couple of years ago, I would have answered the same way. Now, at least in the SF Valley area, these types of things are largely ignored and instead we're asking a lot more CS questions (algorithms, data structures, design patterns, etc). In fact, I'd say about 99% of interviews for a front-end position don't ask ANY CSS questions at all - they're all JS-based. For example, in a recent string of interviewing here for a couple of large SF-based companies and startups, I've encountered questions like re-implementing jQuery, doing the JS for the game Snake, palindrome checkers, longest chain of ascending numbers in an array, shortest path, matching node (given a node in one tree, find the same node in an identical tree), and basically a whole bunch of other questions where only JS skill were assessed.
