Modal Window not scrolling till bottom

Question

I have created a modal using css , html and JavaScript

The issue is it is not scrolling till the very bottom For better reference i have added numbers 1 to 100 in the modal window For some reason it scrolls only till 96 and doesn't scroll any further

Please someone suggest some changes in coding which can resolve this issue ( i am a newbie but i guess it might be something to be done in css)

Nevertheless i am attaching the codes here

$(function() {

  // Get the button that opens the modal
  // read all the control of any type which has class as modal-button
  var btn = document.querySelectorAll(".modal-button");

  // All page modals
  var modals = document.querySelectorAll('.modal');

  // Get the  element that closes the modal
  var spans = document.getElementsByClassName("close");

  // When the user clicks the button, open the modal
  for (var i = 0; i < btn.length; i++) {
    btn[i].onclick = function(e) {
      e.preventDefault();
      modal = document.querySelector(e.target.getAttribute("href"));
      modal.style.display = "block";
    }
  }

  // When the user clicks on  (x), close the modal
  for (var i = 0; i < spans.length; i++) {
    spans[i].onclick = function() {
      for (var index in modals) {
        if (typeof modals[index].style !== 'undefined') modals[index].style.display = "none";
      }
    }
  }

  // When the user clicks anywhere outside of the modal, close it
  window.onclick = function(event) {
    if (event.target.classList.contains('modal')) {
      for (var index in modals) {
        if (typeof modals[index].style !== 'undefined') modals[index].style.display = "none";
      }
    }
  }
})

Add box-sizing: border-box; to your .model class will give you desire result.

$(function() {

  // Get the button that opens the modal
  // read all the control of any type which has class as modal-button
  var btn = document.querySelectorAll(".modal-button");

  // All page modals
  var modals = document.querySelectorAll('.modal');

  // Get the  element that closes the modal
  var spans = document.getElementsByClassName("close");

  // When the user clicks the button, open the modal
  for (var i = 0; i < btn.length; i++) {
    btn[i].onclick = function(e) {
      e.preventDefault();
      modal = document.querySelector(e.target.getAttribute("href"));
      modal.style.display = "block";
    }
  }

  // When the user clicks on  (x), close the modal
  for (var i = 0; i < spans.length; i++) {
    spans[i].onclick = function() {
      for (var index in modals) {
        if (typeof modals[index].style !== 'undefined') modals[index].style.display = "none";
      }
    }
  }

  // When the user clicks anywhere outside of the modal, close it
  window.onclick = function(event) {
    if (event.target.classList.contains('modal')) {
      for (var index in modals) {
        if (typeof modals[index].style !== 'undefined') modals[index].style.display = "none";
