I think you should try JQuery Slider. Get the value from slider and then assign it to font-size in body tag for the page.
check here jQuery UI slider: http://jqueryui.com/demos/slider/

Just get a slider control and then implement the client side events.

The solution is quite simple

Just get jQuery and jQuery ui

HTML

<head>
    <link rel="stylesheet" href="http://code.jquery.com/ui/1.10.2/themes/smoothness/jquery-ui.css"/>
    <script src="http://code.jquery.com/jquery-1.9.1.js"></script>
    <script src="http://code.jquery.com/ui/1.10.2/jquery-ui.js"></script>

</head>

Create the elements

HTML

<div id="slider-range-max"></div>

<p id="text">Text</p>

and change font-size on slide event.

JavaScript

$( "#slider-range-max" ).slider({
    range: "max",
    min: 10,
    max: 70,
    value: 10,
    slide: function( event, ui ) {
      $( "#text" ).css( { fontSize: ui.value} );
    }
  });
