Is it possible to have a different font size for the Catgeory and Subcategory. I want a large font size for the category and a smaller one for the subcategories. I see in the style sheet the one value below controls both, is there anyway to change it?

h4, h5, h6, LABEL, h4.optionName, LEGEND, ADDRESS, .sideBoxContent, .larger{
font-weight: bold;
font-size: 1.25em;
}
