Web Content
Accessibility Guidelines
1. Provide text equivalents for visual information. Provide text
equivalents for all images, applets and image maps.
2. Provide descriptions of important visual information. Provide
descriptions of important information in graphics, scripts, applets, videos
or animations if it is not fully described through text equivalents or
in the document's content.
3. Provide text equivalents for audio information. Provide text
transcripts, text descriptions, or captions of auditory events that occur
in audio and video.
4. Don't rely on color alone. Ensure that text and graphics are
perceivable and understandable when viewed without color.
5. Use markup and style sheets properly. Mark up documents with
the proper structural elements. Control presentation with style sheets
rather than with presentation element and attributes.
6. Supplement markup to aid interpretation of text.
Provide supplemental information to facilitate pronunciation or interpretation
of abbreviated or foreign text.
7. Create tables that transform gracefully. Ensure that tables
have necessary markup to be properly restructured or presented by accessible
browsers and other user agents.
8. Ensure that pages featuring new technologies transform gracefully.
Ensure that pages are accessible when newer technologies are not supported
or are turned off.
9. Ensure user control of time-sensitive content changes. Ensure
that moving, blinking, scrolling, or auto-updating objects or pages may
be paused or stopped.
10. Ensure that direct accessibility of embedded user interfaces. Ensure
that the user interface follows principles of accessible design: device
independent access to functionality, keyboard operability, self-voicing.
11. Design for device-independence. Use features that enable activation
of page elements via input devices other than a pointing device (e.g.
keyboard, voice, etc.)
12. Consider interim solutions. Use interim accessibility solutions
so that assistive technologies and older browsers will operate correctly.
13. Use W3C technologies and guidelines. Use W3C technologies (according
to specification) and follow accessibility guidelines. Where it is not
possible to use a W3C technology, or doing so results in material that
does not transform gracefully, provide an alternative version of the content
that is accessible.
14. Supply context and orientation information. Supply content
and orientation information to help users understand complex pages or
elements.
15. Design clear navigation structures. Use clear navigation structures,
navigation bars, etc. to increase the likelihood that a person will find
what they are looking for at a site.
16. Design for consistency and simplicity. Use consistency and
simplicity to promote comprehension.
