Why Universal Design and Web Accessibility?
Web page access has gained national attention with implementation of the Federal Section 508 of the Rehabilitation Act in June of 2001 that requires, in part, that all federal agencies immediately make web pages accessible for anyone accessing agency web sites. The regulation applies only to federal agencies, not directly to public or private universities, although many campuses around the country have moved quickly to use Section 508 as one guideline. There is general consensus that federal agencies such as the US Dept of Education and the Office for Civil Rights (OCR) will use Section 508 as a guideline when investigating complaints of disability discrimination. OCR, particularly in several California cases of community colleges and California State University (CSU), has been very active in investigating electronic/Internet/computing access issues. For higher education, the Americans with Disabilities Act, and Section 504 of the Rehabilitation Act are the two key federal legislative and civil rights law requiring electronic access under the sections that address "timely and effective communication" and access to all "activities and programs." "Effective communication" has been clearly interpreted to apply to all print and electronic communication. Presently the guidelines that are used most widely by campuses around the country are the Web Acccess Initiative Guidelines. If you click on this site and go to "Frequently Asked Questions" you will find a good summary of information.
The Importance of Web Accessbility
UCI students and employees with disabilities may need web accessibility features. Additionally, many individuals (prospective and new students, parents, outside organizations/agencies, and individuals from anywhere in the US and abroad may use UCI web pages) will have disabilities. Web page access needs to be provided to all individuals, whether or not they are UCI students or employees.
Universal Design for the Web
The intent and scope of universal design is to make the World Wide Web (WWW) accessible for a wide range of people with disabilities. By following the guidlines listed below your website will be robust, standard and accessible to the widest range of users. When developing your website(s) keep in mind that your audience is diverse. Not all users of the WWW use standard graphical browsers. They may be using adaptive technologies such as screen readers or text-based browsers. Some users may have their graphics turned off or may not be able to use to an input device (mouse, keyboard, etc.). Other users may even have physical or cognitive disabilities that impact their viewing of web pages.
Web Accessibility Basic Principles
The links listed below will take you to the W3C's Web Accessibility Content Guidelines (WCAG), the primary resource for web accessibility issues and other information.
The most important points to remember in creating or making your web pages "Priority 1 Accessible" are:
- Follow current web standards. HTML 4.0, Cascading Sytle Sheets (CSS)
- Images and Animations - Use the alt attribute to describe the function of all visuals
- Image Maps - Use client-side MAP and text for hotspots
- Multimedia - Provide captioning and transcripts of audio and descriptions of video
- Hypertext Links - Use text that makes sense when read out of content (For example, avoid 'click here').
- Page Organization - Use headings, lists, and consistent structure. Use CSS for layout and style where possible
- Graphs and Charts - Summarize or use the longdesc attribute
- Scripts, Applets and Plug-ins - Provide alternate content in case active features are inaccessible or unsupported
- Frames - Use NO FRAMES
- Tables - Make line by line reading sensible. Summarize.
- Check Your Work - Validate your website(s) using the W3C's Validation Service and/or the BOBBY Accessibility Checker. Test on a variety of platforms (UNIX, Windows, Macintosh) and browsers (Netscape 3.x-4.x; Internet Explorer 4.x-5.x, Lynx). Use tools, checklist, and guidelines at http://www.w3.org/TR/WAI-WEBCONTENT.
- Refer to the Web Acccess Initiative Guidelines when in doubt.
