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 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 (A virtual style element.)
HTML 3.2 and 4.0, however, support both font size control mechanisms.
