The need for something like this - basic styling because the default display is so bad for raw html - suggests that there's something missing from our browsers. Of course everyone has their own preferences, but being able to add <theme "foo"> at the top of an html page would be very helpful. In many instances the exact styling isn't important as long as there's some styling. It would, among other things, minimize on bandwidth while providing a comfortable experience.
