Animation doesn't work on iOS

Hello guys,

I’m trying to show a form in a kind of modal window.
I set an animation to show the div container after tap/click on a button.

All works good in the preview in the desktop browser, but then when I play it on iOS it doesn’t.
It seems iOS refuses to read the first status as hidden and it shows the div with the form immediately.
As well the close button that trigs the animation to hide the div, works on the desktop browser, and it doesn’t on iOS.

Any idea?
