Otherwise, if(!horizontal) y != block. "bg-pos-y: start" isn't a shorthand for anything else, but it does turn into "bg-pos-y: top" (or bottom) depending on w-m/direction. bg-pos-y is then also an alias for either bg-pos-inline or bg-pos-block, depending on w-m/direction. ~TJReceived on Tuesday, 22 April 2014 01:45:54 UTC
