У меня возникла проблема с созданием адаптивной сетки flexbox, и я надеялся, что кто-то может указать мне правильное направление.

Я хочу, чтобы все.block div должен быть равной высоты, а.bottom div абсолютно позиционируется снизу. Это на самом деле работает в текущем решении, нокогдаh2 заголовок слишком длинный и достигает 2 строк, я хочу, чтобы всеh2 заголовки ряда должны быть одинаковой высоты.

Возможно ли это как-то?

Я сделал Codepen, чтобы проиллюстрировать проблему:http://codepen.io/kenvdbroek/pen/eZKdEQ
