<p id="demo"></p>

<script>
var i = 0;
var txt = "It is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout. The point of using Lorem Ipsum is that it has a more-or-less normal distribution of letters, as opposed to using 'Content here, content here', making it look like readable English.";
var speed = 30;

function typeWriter() {
  if (i < txt.length) {
    document.getElementById("demo").innerHTML += txt.charAt(i);
    i++;
    setTimeout(typeWriter, speed);
