jQuery plugin creates typed text effect.
To use typedText you just need to have jQuery (>= 1.5.x) and typedText loaded in your page:
<script src="http://code.jquery.com/jquery-1.11.0.min.js"></script>
<script src="jquery.typedtext.js"></script>
And call the function on your html element to transform it in a typed text
$('div.text').typedText();
typedText accepts an option like that:
$('div.text').typedText({
delay: 200
});
integer (default: 100)
delay: 100
