Web Accessibility

Universal Design = Universal Access

Applying universal design concepts to your Web site will make it accessible to all Internet users, including those with disabilities, those with graphics turned off, and everyone using a variety of Web browsers and versions (device independence). Site designers and webmasters can take advantage of the DCP's free web accessibility review service to assist in maximizing the effectiveness of their sites.

For more information Project EASI maintains a list of links on web accessibility issues.

• NCAM Web Page Accessibility Symbol
  "This image may be used by webmasters to denote that their site contains accessibility features to accommodate the needs of disabled users. The symbol should always be accompanied by its description and alt-text tag." (Note that this indicates a good-faith effort to use accessible design, but is not linked to specific standards.) (Project discontinued?)

C. General Topics of Relevance (Not Disability-related sites)

HTML

• HyperText Markup Language (HTML) (@W3C)

  HTML is a markup language for hypertext which is used in WWW clients. This site provides an overview of all HTML related materials at W3C and around the web.

XML

• SGML, XML, and Structured Document Interchange (@W3C)

  XML, or Extensible Markup Language is a simplified version of SGML (Standard Generalized Markup Language, an ISO standard system for defining and using document formats), suitable for Internet applications.

Style Sheets

• Web Style Sheets (@ W3C)

  "Style sheets describe how documents are presented on screens, in print, or perhaps how they are pronounced.  By attaching style sheets to structured documents on the Web (e.g. HTML), authors and readers can influence the presentation of documents without sacrificing device-independence or adding new HTML tags." (from W3C)
