And not even, apparently, that a lower z-index on e.g. the region-beforebs content will make it appear below the content of the region-body. Since IIUC the stacking contexts arenbt the same. > Perhaps a combination of the block-container, in a perimeter region, > with a lower z-index than the content of the body region (which > 7.30.18 implies is zero) would do the trick. I'd appreciate it if > someone on the committee would comment on this. Indeed, actually this is not obvious whether the trick above will work or not. In practice it should be tested with the FO processor that will be used in production. bYour mileage may vary.b Vincent -- Vincent Hennebert Anyware Technologies http://people.apache.org/~vhennebert http://www.anyware-tech.com Apache FOP Committer FOP Development/Consulting
