GED-GEN creates web page files using Hypertext Markup Language (HTML). HTML is a set of rules (i.e., a standard) that describes the content of web pages. The standard promotes a uniform way of interpreting web pages for consistent display on all Internet browsers.
Generally, not all web pages conform to the HTML standard, and those that do may not conform to the strictest standard. Therefore Internet browsers typically interpret non-standard elements they encounter in a web page. They can still display a non-standard web page, but since different browsers interpret them differently, the page may appear differently in each browser.
That said, each Internet browser also interprets the HTML standard differently. Even a standard HTML web page may appear differently in each browser. The interpretation of the HTML standard also affects "validator" programs. Such programs measure the conformance of a web page to the HTML standard. Some validators may miss certain errors while others may be overly critical.
The basic output of GED-GEN conforms to the HTML 4.01 Transitional standard. Each web page generated includes a Document Type Definition (DTD) indicating this conformance. A sample set of web pages was successfully validated using the HTML validation facility at www.w3c.org 
.
When you customize the web pages that GED-GEN creates, you may include your own HTML syntax in the following areas:
The HTML syntax samples provided conform to the HTML 4.01 Transitional standard.
Most web pages, whether standard or not, will display satisfactorily in most Internet browsers. Any custom HTML statements you add may cause GED-GEN to violate its conformance to the standard. If you are concerned about conformance, you should validate the web pages created by GED-GEN after you have added your custom HTML. The HTML validation facility at www.w3c.org is recommended.
