There are two lists of all HTML 4.01 elements and attributes in the Chapter 13 "Index of HTML elements and attributes" in . "Elements that are deprecated in HTML 4.01 are followed by an asterisk (*). Elements that are obsolete in HTML 4.01 or don't exist in a W3C specification of HTML (2.0, 3.2, 4.01) do not appear in this table."  The second "index lists some attributes in HTML 4.01 that affect accessibility and what elements they apply to. The first column of this table links to the definition of the attribute in the HTML 4.01 specification (). Attributes and elements that are deprecated in HTML 4.01 are followed by an asterisk (*). Attributes and elements that are obsolete in HTML 4.01 or don't exist in a W3C specification of HTML (2.0, 3.2, 4.01) do not appear in this table. Attributes that apply to most elements of HTML 4.01 are indicated as such; please consult the HTML 4.01 specification for the exact list of elements with this attribute." 
"In order to ensure that users can control styles, CSS2 changes the semantics of the "!important" operator defined in CSS1. In CSS1, authors always had final say over styles. In CSS2, if a user's style sheet contains "!important", it takes precedence over any applicable rule in an author's style sheet. This is an important feature to users who require or must avoid certain color combinations or contrasts, users who require large fonts, etc." 
If you like to define fonts in your web pages you avoid using deprecated HTML elements and attributes. The W3C recommends using the following techniques:
Instead of using deprecated presentation elements and attributes, use the many CSS properties to control font characteristics like 'font-family', 'font-size', 'font-size-adjust', 'font-stretch', 'font-style', 'font-variant', and 'font-weight'.
