2010-05-31 23:04:29: Created issue 'Chaining regions' nickname owned by Bert Bos on product CSS3 Template Layout, description 'It could, under certain conditions, be possible to support complex shapes for slots, by creating multiple simple slots and describing in which order they are filled, e.g.:
"a . b"
". . ."
"c . d";
chains: a b c d;
This would create one chain, consisting of the four simple slots in the given order.
However, if the slots of a chain have a size that depends on their content, determining that size becomes an optimization problem, which might require multiple passes. (It's not a problem if all slots have an "outside-in" size, or if only the last slot in a chain has a size that depends on its content. Or at least it's not a new problem: The algorithm in that case is the same as for pagination.)' non-public [Bert Bos]
