Good but fails validation

This page uses the Check list provided by the W3C website.

Priority 1 checkpoints

In General

1.1 Provide a text equivalent for every non-text element.

2.1 Ensure that all information conveyed with colour is also available without colour.

4.1 Clearly identify changes in the natural language.

6.1 Organise documents so they may be read without style sheets.

6.2 Ensure that equivalents for dynamic content are updated when the dynamic content changes.

7.1 Until user agents allow users to control flickering, avoid causing the screen to flicker.

14.1 Use the clearest and simplest language appropriate for a site's content.

Images and image maps

1.2 Provide redundant text links for each active region of a server-side image map.

9.1 Provide client-side image maps instead of server-side image maps except where the regions cannot be defined with an available geometric shape.

Tables

5.1 For data tables, identify row and column headers.

5.2 For data tables that have two or more logical levels of row or column headers, use markup to associate data cells and header cells.

Frames

12.1 Title each frame to facilitate frame identification and navigation.

Applets and scripts

6.3 Ensure that pages are usable when scripts, applets, or other programmatic objects are turned off or not supported. If this is not possible, provide equivalent information on an alternative accessible page.

Multimedia

1.3 Until user agents can automatically read aloud the text equivalent of a visual track, provide an auditory description of the important information of the visual track of a multimedia presentation.

1.4 For any time-based multimedia presentation (e.g., a movie or animation), synchronise equivalent alternatives (e.g., captions or auditory descriptions of the visual track) with the presentation.

And if all else fails

11.4 If, after best efforts, you cannot create an accessible page, provide an alternative.
