Why is this script not working?

It seems to work everywhere else on other web editors, but when I paste it into shopify it stops working.

<link href="https://fonts.googleapis.com/css?family=Raleway:200,100,400" rel="stylesheet" type="text/css" />
<h1>This pen is
<span
class="txt-rotate"
data-period="2000"
data-rotate='[ "nerdy.", "simple.", "pure JS.", "pretty.", "fun!" ]'></span>
</h1>
<h2>A single &lt;span&gt; is all you need.</h2>

<script>
var TxtRotate = function(el, toRotate, period) {
this.toRotate = toRotate;
this.el = el;
this.loopNum = 0;
this.period = parseInt(period, 10) || 2000;
this.txt = '';
this.tick();
this.isDeleting = false;
};

TxtRotate.prototype.tick = function() {
var i = this.loopNum % this.toRotate.length;
var fullTxt = this.toRotate[i];

if (this.isDeleting) {
this.txt = fullTxt.substring(0, this.txt.length - 1);
} else {
this.txt = fullTxt.substring(0, this.txt.length + 1);
}

this.el.innerHTML = '<span class="wrap">'+this.txt+'</span>';

var that = this;
var delta = 300 - Math.random() * 100;

if (this.isDeleting) { delta /= 2; }

if (!this.isDeleting && this.txt === fullTxt) {
delta = this.period;
this.isDeleting = true;
} else if (this.isDeleting && this.txt === '') {
this.isDeleting = false;
this.loopNum++;
delta = 500;
}

setTimeout(function() {
that.tick();
}, delta);
};

window.onload = function() {
var elements = document.getElementsByClassName('txt-rotate');
for (var i=0; i<elements.length; i++) {
var toRotate = elements[i].getAttribute('data-rotate');
var period = elements[i].getAttribute('data-period');
if (toRotate) {
new TxtRotate(elements[i], JSON.parse(toRotate), period);
}
}
// INJECT CSS
var css = document.createElement("style");
css.type = "text/css";
css.innerHTML = ".txt-rotate > .wrap { border-right: 0.08em solid #666 }";
document.body.appendChild(css);
};
</script>
