    This code manipulates document.body.style.fontSize.
    Other elements sized using relative measures (em's or %)
    in style sheets will adjust accordingly. 
    Exclude elements (i.e., selectors) by using pixels, points or 
    constants (small, medium, etc.) to set their font-size in style sheets.
