If accessibility cannot be accomplished in any other way, provide a text-only page with equivalent information or functionality. Update the content of the text-only page whenever the primary page changes.
Rationale
If after examining all the checkpoints, you find that compliance with the checklist cannot be achieved any other way, a text-only age with equivalent information and functionality, should be provided to make the Web site accessible. However, this is not the ideal solution. The text-only pages must be maintained and updated in congruence with the primary Web pages.
For additional information regarding the difficulties of text-only sites, please read the following helpful article from AccEase: Text-only websites: five key difficulties (link resides outside of ibm.com).
Techniques for Text-only pages
The following techniques and examples support Checkpoint 15 from the IBM Web Accessibility Checklist.
The following techniques are the minimum required to meet this checkpoint:
In order to keep the equivalent information and functionality for the primary Web page and the text-only page, publish both versions at the same time. In addition, from the primary Web page, make the link to the text-only page easily identifiable to the user.
The BBC provides a tool which can be used to create an automatic text-only version of a Web page. Betsie (BBC Education Text to Speech Internet Enhancer) is a free server-side solution which can be downloaded at http://www.bbc.co.uk/education/betsie/index.html.
Testing
Test the Web site to ensure that it complies with accessibility requirements.
Tools
There are no tools required to test this checkpoint.
Techniques
The following technique is required to verify this checkpoint:
| Action | Result | |
|---|---|---|
| 1 | If a Web site has a text-only page, view the page with a graphical browser. Compare the content of the graphical page to the text-only page. | Pass: The primary Web page and the text-only page have equivalent information and functionality. Fail: The text-only page does not have equivalent function and content. |
