Я так близок к тому, чтобы добиться идеального эффекта, но я столкнулся с небольшим небольшим ухабом на дороге.
У меня есть система обмена сообщениями с основным div (# message-viewer), который содержит поток сообщений. Я хотел бы, чтобы, когда пользователь просматривал это на своем iPad и проводил вправо (в любом месте внутри этого div), этот # message-viewer соскальзывал с экрана, а # div2 появлялся с левой стороны экрана. .
Надеюсь, это имеет смысл ... Я прикрепил свой код. Я думаю, что Padalicious код может мешать прокрутке Y ...
Спасибо за помощь!
