Probably the most useful tag for managing your text's appearence is
the FONT tag.
<FONT FACE="arial,helvetica">
this text is in arial or helvetica dending on your computer. </FONT>
All text between the <FONT> & </FONT> will be displayed
in the indicated font, with the preferred font in the first position.
Place commas between font names.
If the computer does not have any of the fonts you listed, it will
use it's default font face.
You can set the following attributes:
COLOR="#FF0000" would result in red text.
FACE="MS Comic Sans, helvetica" uses Comic sans if available, otherwise helvetica.
SIZE="2" would result in somewhat small text.
SIZE="5" would result in big text.
SIZE="+1" creates fonts one size larger than the current font.
SIZE="-1" creates fonts one size smaller than the current font.
