iPhone browsers (chrome and safari) output different compared to other browsers 1

[jason.lex]

I have made a mobile version of the page and need to center a button over an image.

I used the example given here,
but for some reason the actual iPhone browsers (Chrome and Safari) both showing that the button isn't actually centered like it is in the desktop or ChromeTools.
Even Android browser shows the buttons is centered. Just not browsers in iPhone....

Is there a way to fix it so that both Android and iPhone shows the same result?

Try adding

-webkit-transform: translate(-50%, -50%);

to your CSS from the Example

/* Style the button and place it in the middle of the container/image */
.container .btn {
  position: absolute;
  top: 50%;
  left: 50%;
  transform: translate(-50%, -50%);
  -ms-transform: translate(-50%, -50%);
*******add it here**********
  background-color: #555;
  color: white;
  font-size: 16px;
  padding: 12px 24px;
  border: none;
  cursor: pointer;
  border-radius: 5px;
}

Not 100% sure if it helps though.
