Why does input move out in iOS?

Question

css

There is an online callback form on the maxg5.ru website .
When entering from Iphone and trying to display data in the phone field, the carriage jumps to the description field.
I was recommended to add the following class to the body when opening a modal window:

show {
  overflow: hidden !important;
    position: fixed;
    width:73%;
}

I added like this:

body .popup {
  overflow: hidden !important;
    position: fixed;
    width:73%;
}

But for some reason, the carriage still moves out on the Iphone.

Answer 1

So I recommended that you add it not to popup, but to body , and only when the window is opened.
Then delete the body class
. You were offered a run-in solution, and you do it your way, and then say that it doesn’t work.
