Hide overflow when scrolling

Question

I'm trying to design a webpage where the page content shows within an iPhone screen but I cannot get the overflow to work correctly in that all overflow is being shown.

function getWidth() {
  if (self.innerWidth) {
    return self.innerWidth;
  }

  if (document.documentElement && document.documentElement.clientWidth) {
    return document.documentElement.clientWidth;
  }

  if (document.body) {
    return document.body.clientWidth;
  }
}

function getHeight() {
  if (self.innerHeight) {
    return self.innerHeight;
  }

  if (document.documentElement && document.documentElement.clientHeight) {
    return document.documentElement.clientHeight;
  }

  if (document.body) {
    return document.body.clientHeight;
  }
}

function setScreen() {
  var img = document.getElementById('iphone');
  //or however you get a handle to the IMG
  var myWidth = getWidth();
  var width = String(Math.round(getWidth() / 2 - img.clientWidth / 2 + (img.clientWidth / 525) * 94)) + 'px';
  var height = String(Math.round(getHeight() / 2 - img.clientHeight / 2 + (img.clientWidth / 915) * 170)) + 'px';
  document.getElementById("screen").style.paddingTop = height;
  document.getElementById("screen").style.paddingLeft = width;
  document.getElementById("screen").style.paddingRight = width;
  document.getElementById("screen").style.paddingBottom = height;
  console.log("Image Width: " + img.clientWidth);
  console.log("Screen Width: " + myWidth);
  console.log("Calculated PaddingLeft: " + width);
}

window.onresize = function() {
  setScreen();
}
setScreen();

.screen {
  padding-top: 15%;
  padding-left: calc(50% - 262px);
  position: absolute;
  overflow: hidden;
  display: block;
}
.phone-image {
  position: fixed;
  top: 0;
  bottom: 0;
  left: 0;
  right: 0;
  max-width: 100%;
  max-height: 100%;
  margin: auto;
  display: block;
}

<img src='http://s11.postimg.org/vcchvwjub/iphone.jpg' id='iphone' class="phone-image">
<div id="screen" class="screen">
  <p>This is where my text goes and it should now wrap and only show within the phone, I think.</p>
</div>

I've put it in a jsfiddle and would appreciate to know what I've got wrong.

Many thanks

no, I meant for the text not to show outside the iphone screen but when I scroll the text shows both above and below — HenryM

Maybe its work for you.

You need a container for your text and image, and play with relative and absolute positions.

Remember to hide the scrollbar, his width different between browsers and you don't want the text container change his width.

::-webkit-scrollbar {
  display: none;
}
body {
  font-size: 100%;
  padding: 0;
  margin: 0;
}
p {
  font-size: 0.8em;
}
#container {
  position: relative;
  width: 50%;
  margin: 0 auto;
}
.screen {
  overflow: scroll;
  width: 60%;
  height: 61%;
  position: absolute;
  top: 14%;
  left: 20%;
}
.phone-image {
  width: 100%;
  display: block;
}

<div id="container">
  <img src='http://s11.postimg.org/vcchvwjub/iphone.jpg' id='iphone' class="phone-image">
  <div id="screen" class="screen">
    <p>This is where my text goes and it should now wrap and only show within the phone, I think.</p>
