Javascript DOM onwheel Event via HTML Tag onwheel function

Introduction

In JavaScript: 

object.onwheel = function(){
       myScript};

This example uses the HTML DOM to assign an "onwheel" event to a DIV element.

A function is triggered when you roll the mouse wheel over div.

The function sets the font-size of div to 35 pixels.
