You have used the attribute named above in your document, but the document type you are using does not support that attribute for this element. This error is often caused by incorrect use of the "Strict" document type with a document that uses frames (e.g. you must use the "Transitional" document type to get the "target" attribute), or by using vendor proprietary extensions such as "marginheight" (this is usually fixed by using CSS to achieve the desired effect instead).
This error may also result if the element itself is not supported in the document type you are using, as an undefined element will have no supported attributes; in this case, see the element-undefined error message for further information. How to fix: check the spelling and case of the element and attribute, (Remember XHTML is all lower-case) and/or check that they are both allowed in the chosen document type, and/or use CSS instead of this attribute.

Lynx Viewer This service allows web authors to see what their pages will look like (sort of) when viewed with Lynx, a text-mode web browser. Note: for best results, you should download a copy of Lynx itself and run it locally on your own machine, rather than use this service, if you can.
That will also let you view pages on your internal network that my machine can't get to. You may put the "Lynx Inspected" icon on your page if you wish. Note: The version of Lynx I'm using is 2.8.4rel.1, as of Dev 14 2003. |- Lynx uses an 80-column output.

Abstract These guidelines explain how to make Web content accessible to people with disabilities. This is a reference document for accessibility principles and design ideas.

"Media models" are recognizable combinations of color, imagery, layout and graphical treatment that people are used to seeing in advertising, television shows, movies, video games and other media.
People associate different models with the messages they are used to getting in those forms ... black and white photographs accompanied by closely set text in narrow columns is a simple model associated with newspapers, so the use of these elements in combination may suggest journalism, accuracy of fact, realism and authenticity. By observing the components of media models you can adopt their "looks" and use them to encourage the response you want from your audience.
Remember that people seek out different media models as cues to the experiences they will get, and they are not always in the mood to have the same kind of experience.

Test your Site for Accessibility with Cynthia Says ™ ADA Coordinator, City of San Jose, CA USA Written and Presented on June 17, 1998 at the request of the American Bar Association for their National Conference "In Pursuit . . . A Blueprint for Disability Law and Policy" Although it may seem that the World Wide Web has been like the Wild, Wild, West --where there are no laws and each frontier web site is on its own, there are significant legal and practical reasons for ensuring web accessibility. By web accessibility I am referring to the design of a webpage that embraces the requirements of Universal Design in order to ensure that all users can access the information on the page: Universal Design calls for the development of information systems flexible enough to accommodate the needs of the broadest range of users of computers and telecommunications equipment, regardless of age or disability.

A-Prompt (Accessibility Prompt) is a software tool designed to help Web authors improve the usability of Web pages created in HTML format. A-Prompt first evaluates an HTML Web page to identify barriers to accessibility by people with disabilities. A-Prompt then provides the Web author with a fast and easy way to make the necessary repairs. The tool's evaluation and repair checklist is based on accessibility guidelines created and maintained by the Web Accessibility Initiative of the World Wide Web Consortium .
By taking this approach, A-Prompt helps Web authors to include HTML features which widen the range of users who can access their website. As well as providing better access for people with disabilities, the resulting Web pages are generally improved for all people and in a larger variety of circumstances. For example, the inclusion of text alternatives for all images makes it possible to understand Web pages in a low-bandwidth text-only situation.
