Section 508 Reference Guide - 1194.22 Web-based Intranet and Internet Information and Application Standards, In Other Words
1194.22(a) Provide text equivalents: For any non-text elements (e.g., logos, pictures, icons), provide an equivalent text description.
1194.22(b) Synchronize multimedia alternatives: The timing of audio descriptions, captions, or other alternatives must be synchronized in online multimedia presentations.
1194.22(c) Supplement color coding: Design web pages so that all information is color independent. The importance of information should be based on context (e.g., location or text content), markup (e.g., HTML heading levels), or other means accessible to AT and to users who have difficulty perceiving colors.
1194.22(d) Readability without styles: Web pages should be readable and accessible based on content rather than style formatting.
1194.22(e) Server-side image maps: For every linked region in a server-side image map there must be an equivalent text link.
1194.22(f) Client-side image maps: When an image map is provided in a web application or page, it must be implemented as a client-side image map, unless its regions are so complex that it must be defined as a server-side image map.
1194.22(g) Simple table headers: Data tables must contain meaningful row and column headers that are properly associated with the data. (Decorative or layout tables should not contain headers.)
1194.22(h) Complex table headers: In complex data tables, data must be explicitly associated with the appropriate headers. That is, for any cell in a complex data table, the user should be able to identify meaningful headers that explain the significance of that cell's data. (Decorative or layout tables should not contain headers.)
1194.22(i) Identify frames with titles: Web pages that use frames must include title markup for frame identification and navigation.
1194.22(j) Avoid fast flashing/blinking: Design web pages so that flicker on the screen is nonexistent, or very slow (e.g., one flicker per second), or very fast (at least fifty-five flickers per second).
1194.22(k) Providing text-only pages: When a website cannot comply with the provisions of 1194.22 in any other way, a text-only equivalent of the site's content shall be provided to users. Whenever the content of the non-compliant page is changed, the text-only site must be updated as well.
1194.22(l) Identify script information: For all websites that use scripts to generate or display content, or to create interface elements, the information provided through that script must be accessible to AT.
1194.22(m) Providing required plug-ins: If a web page requires an application external to a user's browser (e.g., an applet or plug-in) to view content, the application must conform to 1194.21 Software Applications and Operating Systems standards. Also, the web page must provide a link to the application.
1194.22(n) Providing electronic forms: Electronic forms in products must be accessible to AT. This includes the fields in the form, all information required to complete the form, and any functions used to submit the form.
1194.22(o) Skipping repetitive links: For web pages or applications with navigation links that occur more than once, a means must be provided for users to skip such information.
1194.22(p) Interactive system timeouts: Alert the user whenever a time-critical action is required on their part. The user must be given enough time to extend the response time.
