This element applies a larger size font formatting to text (in
relation to the default font size.) It seems to be the HTML 3 answer to the
FONT element (introduced by Netscape and Internet Explorer which runs
counter to general HTML ideology of divorcing display details from
content.) BIG (a virtual style element) and its companion element SMALL
answer the needs of having alternate character level elements for controlling
font size while also not being specific in HOW to display the contents.
HTML 3.2 and 4.0, however, support both font size control mechanisms.
