The following table indicates what claims are indicated by your user agent regarding the implementations of the W3C Document Object Model Recommendations.
A list of W3C DOM Recommendations is available at http://www.w3.org/DOM/DOMTR.
If you get a year in a cell, your browser does not claim to support the DOM module for a given DOM Level. The year in the cell is the year of the release of the W3C DOM Recommendation that defines the DOM module.

Note: The XML and HTML modules require to have support for the core methods. With DOM Level 2, a DOM can implement the core methods separatly and claim support for the Core module. With Level 1, there is no Core module but core methods must still be supported with DOM Level 1 XML and HTML.
This page uses primarily the W3C DOM Level 1 Recommendation and relies on the HTML 4.01 handling in your user agent. The contents inside the table is changed via a script using the DOM Level 1 core methods which must be supported by any user agent that claims to support DOM. Colors are also changed using methods defined in the DOM Level 2 CSS2 module and, given that this module was defined to be backward compatible with existing practices, you may see changes in the colors even if the DOM implementation does not claim to support the DOM Level 2 CSS2 module, or does not support the DOM Level 1 core methods properly.
