3:8 Provide Equivalent Pages

Relative Importance:

Relative Importance rating of 3 out of 5

Strength of Evidence:

Strength of Evidence rating of 2 out of 5

Document Type: Guideline


Topic:

Accessibility


Guideline:

Provide text-only pages with equivalent information and functionality if compliance with accessibility provisions cannot be accomplished in any other way


Comments:

When no other solution is available, one option is to design, develop, and maintain a parallel Web site that does not contain any graphics. The pages, in such a Web site should be readily accessible, and facilitate the use of screen readers and other assistive devices.

As a rule, ensure that text-only pages are updated as frequently and contain all of the same information as their non-text counterparts. Also inform users that text-only pages are exactly equivalent and as current as non-text counterparts.
