That should be 'overflow-style: paged' I believe, see the Marquee 
module[2]. 'Overflow' determines *whether* there is a scrolling 
mechanism, 'overflow-style' specifies what *kind* of scrolling mechanism.

There are so far three kinds, and they can often be combined, in the 
sense that one is used for the horizontal direction and another for the 
vertical one:

   - a scrollbar or similar continuous, interactive mechanism, such as a
     hand cursor or 2D pager,
   - a marquee effect, either vertical or horizontal (i.e., a
     non-interactive mechanism),
   - or a page flipper, something like a dog's ear in the corner, or an
     overlay of next/previous buttons.

I wouldn't *require* the UA to use a dog's ear, but that is at least one 
of the known GUIs for flipping pages. UAs may use something else, just 
as they may use something else instead of scrollbars.
