for one element you could do:
el.setStyle('font-size', el.getStyle('font-size').toInt() - 1);
Since you're using $$ you're working with a collection of elements, so you
need to loop over them, for example with .each:
$$('ul.menu').each(function(el){
el.setStyle('font-size', el.getStyle('font-size').toInt() - 1);
});
In case $$('ul.menu') only has one element, you can use var el =
$E('ul.menu'); instead to get that element. (note: in >= 1.2 that's
document.getElement)
