It is not obvious whether it applies to tables. In Netscape, for example, BASEFONT does not affect the font size within tables. (Thus, to affect the font size within tables you must insert font changing elements into each cell!)
The actual font sizes used depend on the browser. See rendering notes about the FONT element.
|attribute name||possible values||meaning|
|SIZE||string||size of the font (1 - 7)|
It is not obvious from the HTML 3.2 Reference Specification whether the SIZE attribute here follows the same rules as in the FONT element or has to be just an unsigned integer.
<P>This is text with default font size (3).</P> <BASEFONT SIZE=5> <P>This is text with font size 5 with <FONT SIZE=1>some text</FONT> inserted with font size 1.</P>
Use FONT or, more preferably, SMALL or BIG to set font size locally (but notice that paragraph breaks are not allowed within FONT.)
BASEFONT can be regarded as a global counterpart for FONT with SIZE. In a sense, BODY with TEXT is a global counterpart for FONT with COLOR.
