You need the same number of `` elements as `` elements in each row. — davidkonrad, Jul 12 '16 at 07:23
@davidkonrad You should post that as an answer so it's more obvious for any future readers (even though it was such a minor change). — Chris H., Jul 12 '16 at 15:22
@ChrisH. - you are more than welcome to answer yourself :) If the question was tagged with javascript or jquery, _and_ OP had higher rep, I guess I would have closed it using the dupehammer (mjolnir) there is so many derivations over this question already. But you are right, if the question remain it certainly deserves an answer. — davidkonrad, Jul 12 '16 at 15:45
