http://dev.w3.org/csswg/css3-flexbox/#flexibility currently defines the syntax of the 'flex' property as: Value: [[ <pos-flex> <neg-flex>? ]? && [<preferred-size>]?] | none This allows an empty value since the left side of the | reduces to a? && b?. I suspect what was intended was simply to use || without any use of ? marks on its subparts, i.e.: Value: [ [ <pos-flex> <neg-flex>? ] || <preferred-size> ] | none which allows one or both in either order, but doesn't allow neither. (This is in response to a question from Daniel Holbert to me about what the syntax meant.) (Also, a few paragraphs below there's a typo "specifiex".) -David -- 𝄞 L.
