Accessible Web Site Design
- What Does An "Accessible Web Site" Mean?
- An accessible web site is one that does not exclude people with visual, aural, learning, or physical disabilities.
Universally accessible web sites should:
- Provide alternate descriptions of graphical elements
- Provide headers for columns and rows in tables that contain data
- Use identifying language for links
- Have high contrast between background and text
- Meet Section 508 Standards
- Why Is Accessibility Necessary?
- Accessibility allows your information to be available to all users. Ask the following questions about your web site accessibility:
- Is your site's color contrast sufficient for visually impaired users?
- Can a user who is blind or visually impaired understand the content of your graphics, charts and tables?
- Can a user who is deaf or hearing-impaired understand the audio on your web site?
- Is your web site too cluttered with graphics, links, or flashing text for someone with a visual or learning disability?
- Can a user without state-of-the-art hardware access information from your site?
- What Is Universal Design?
Universal Design (UD). UD is the "design of products and environments to be usable by all people, to the greatest extent possible, without the need for adaptation or specialized design." (Center for Universal Design, NC State University) http://www.ncsu.edu/project/design-projects/udi/)
Applications with accessible code empower people who are visually impaired to interact with personal computers, PDAs and the Internet. This is achieved by enabling their screen reading software to narrate document text, give directions for operating programs and describe graphics, photos, charts, tables, menus and navigation controls.
Audio is inaccessible to deaf users, therefore text is needed. Users who are deaf depend on web designers to provide captioned text that is synchronized with audio clips on the Web site In addition, many users will appreciate being able to read the text of audio elements.
Users with learning disabilities sometimes have difficulty comprehending Web sites that are cluttered or disorganized. All users will benefit from well designed sites.
Many Internet users have older computers or slow Internet connections. If your audience includes schools, libraries, rural areas or international users, then many visitors may have barriers that limit access to your site. Web content that requires high-speed internet connections is not accessible to all.
- Do Accessible Sites Have A Special Look?
- Most accessible web features are developed at the source code level to interact with software that accommodates people with disabilities. Some features like alternative graphic descriptions can be accessed by all users.
- How Do I Begin?

- Turn off images
- Turn off the sound
- Change the font size
- Set screen resolution to 640x480
