I use iframe with image carousel. And this iframe is not scrollable on mobile. You can not scroll the page down when you touch this iframe. Is it possible to do something? Here is the page with such iframe.
If you see the code, you can find
<iframe frameborder="0" marginwidth="0" marginheight="0" scrolling="no" allowfullscreen="true" srcdoc="" id="iframe:0" style="width: 100%; min-width: 100%; max-width: 100%; height: 100%; min-height: 100%; max-height: 100%; margin: 0px; padding: 0px; border: 0px;"></iframe>
There, you can see scrolling="no".
This stops scrolling.
So you can replace that excluded scrolling="no" iframe tag.
<iframe frameborder="0" marginwidth="0" marginheight="0" allowfullscreen="true" srcdoc="" id="iframe:0" style="width: 100%; min-width: 100%; max-width: 100%; height: 100%; min-height: 100%; max-height: 100%; margin: 0px; padding: 0px; border: 0px;"></iframe>
