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 this bit 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  ...  element with the  ...  element, or be forced to render the subscript the same size as the normal text, by compounding the  ...  element with the <BIG> ... </BIG> element. The exact appearance of the subscript text will change depending on any  and <BASEFONT SIZE=...> settings, if specified.

TITLE="informational ToolTip"
The Internet Explorer 4.0 (and above) specific TITLE attribute is used for informational purposes. If present, the value of the TITLE attribute is presented as a ToolTip when the users mouse hovers over the  section.

LANG="language setting"
The LANG attribute can be used to specify what language the  element is using. It accepts any valid ISO standard language abbreviation (for example "en" for English, "de" for German etc.) For more details, see the Document Localisation section for more details.

LANGUAGE="Scripting language"
The LANGUAGE attribute can be used to expressly specify which scripting language Internet Explorer 4.0 uses to interpret any scripting information used in the  element. It can accept values of vbscript, vbs, javascript or jscript. The first two specify the scripting language as Visual Basic Script, the latter two specify it as using Javascript (the default scripting language used if no LANGUAGE attribute is set.

CLASS="Style Sheet class name"
The CLASS attribute is used to specify the  element as using a particular style sheet class. See the Style Sheets topic for details.

STYLE="In line style setting"
As well as using previously defined style sheet settings, the  element can have in-line stylings attached to it. See the Style Sheets topic for details.

ID="Unique element identifier"
The ID attribute can be used to either reference a unique style sheet identifier, or to provide a unique name for the  element for scripting purposes. Any  element with an ID attribute can be directly manipulated in script by referencing its ID attribute, rather than working through the All collection to determine the element. See the Scripting introduction topic for more information.

Every  element in a document is an object that can be manipulated through scripting. Note that scripting of the  element/object is only supported by Internet Explorer 4.0 in its Dynamic HTML object model. Netscape does not support direct scripting of the  element at all.
