Throughout Part II, compatibility tables accompany most entries. A number shown for an item indicates the version of the designated browser or web standard in which the term was first introduced. If an item premiere predates Navigator 2, Internet Explorer 3, or HTML 3.2, it is assigned the value "all". If an item is not supported by a browser or standard as the book went to press, it is assigned the value "n/a". If an item has been removed from a browser, a less-than symbol precedes the version that no longer supports the item (e.g., <6). And if an item is available in only one browser version, the number is surrounded by vertical bars (e.g., |4|).
