<!-- the script -->
<script>
  $( ".counter" ).each(function() {
	// Get initial value (span value) as a number
	var initial_value = +($(this).text());
	// Get increment value inside the data-increment-value HTML5 tag
	var increment_value = $(this).data("increment-value");
	// Get increment time inside the data-increment-time HTML5 tag
	var increment_time = $(this).data("increment-time");
	// Define a variable for $(this)
	var that = this;
	
	setInterval(function(){
		// increment the value
		initial_value += increment_value;
		// define the value as text of the span (this) // each millisecond
		$(that).text(initial_value.toFixed(2));
