The FONT tag lets you control attributes of your text. For example: 
<FONT size=+2 color="#006000">
	This is a larger font 
	size, colored green
</FONT>
<BR> <BR>
	This is text without 
	modification.
<BR> <BR>
<FONT size=-1 face="courier">
	This is a smaller font 
	size in courier type.
</FONT>
The output of this will appear as follows:

This is a larger font size, colored green

This is text without modification.

This is a smaller font size in courier type
