Scrollable iFrame with position:sticky element in iOS

Question

I want to create an scrollable iFrame with a position:sticky element inside, that also works on iOS.

iOS does not respect the iFrames height:340px setting, a workaround to still make it scrolling is a container div with overflow-y:auto;-webkit-overflow-scrolling: touch; (see Iframe scrolling iOS 8 ).

But when only the outside div is scrolling the position:sticky is not working. Is there any other solution to making the iFrame scrollable?

Answer 1

Okay, I found the solution - wrapping all iFrame content makes the div container obsolete:

#wrap {
    position: fixed;
    top: 0;
    right:0;
    bottom:0;
    left: 0;
    overflow-y: scroll;
    -webkit-overflow-scrolling: touch;
}
