The Subscript element specifies that the enclosed text should be displayed as a subscript, and if practical, using a smaller font (compared with normal text).

This is the main text, with <SUB>this bit</SUB> being subscript.

Would render as :

This is the main text, with this bit being subscript.

NOTE : The selected text will be made a superscript to the main text, formatting the selected text slightly smaller than the normal text. Netscape and the Internet Explorer can be forced to make subscripts even smaller by compounding the <SUB> ... </SUB> element with the <SMALL> ... </SMALL> element, or be forced to render the subscript the same size as the normal text, by compounding the <SUB> ... </SUB> element with the <BIG> ... </BIG>> element. The exact appearance of the subscript text will change depending on any <FONT SIZE=...> and <BASEFONT SIZE=...> settings, if specified.

<SUB> can also take the CLASS, ID and STYLE attributes to allow style sheet definitions to be applied to it. For more details of these attributes, see the Style Sheets topic.
