It would work much more reliably, and due to not needing special authoring work it would work on most files instead of almost none. It would be much more flexible; UAs could, for example, vary the number of displayed lines and scrolling speed based on screen usage with the chosen font. (I doubt that there's actually any demand for roll-ups, so it would probably never be implemented, but that's how it's supposed to work.) There isn't any; but the UA still needs to know which lines of text fall into the same grouping so that they make one text block that can/is 'move up' (jump or scroll). It's that grouping that we're mostly discussing. I don't see anything 'brittle' about CSS transitions, by the way. David Singer Multimedia and Software Standards, Apple Inc.
