How to get popup keyboard height on mobile devices in browser (ios)?

Question

iOS

There is a web application. It is required to show the element strictly above the pop-up keyboard.
If with android this can be achieved through the viewport, then ios categorically does not see the keyboard and the size of the viewport, both with the keyboard and without it, does not change.
I tried to calculate the viewport through timeout, but it still does not change.

Answer 1

Try using VisualViewport - works since iOS 13, shows height minus keyboard height.
