Accessibility Issues
Images
A text equivalent for every non-text element shall be
provided (e.g., via "alt", "longdesc," or in element content).
Redundant text links shall be provided for each active
region of a server-side image map.
Client-side image maps shall be provided instead of server-side
image maps except where the regions cannot be defined with
an available geometric shape.
General
Web pages shall be designed so that all information conveyed
with color is also available without color for example from
context or markup. Documents shall be organized so they are readable without
requiring an associated style sheet. Pages shall be designed to avoid causing the screen to
flicker with a frequency greater than 2 Hz and lower than
55 Hz. A method shall be provided that permits users to skip
repetitive navigation links. When a timed response is required, the user shall be alerted
and given sufficient time to indicate more time is required.
Tables Row and column headers shall be identified for data tables
as well as a method to relate the data cells to those headers.
Markup shall be used to associate data cells and header
cells for data tables that have two or more logical levels
of row or column headers.
Frames Frames shall be titled with text that facilitates frame
identification and navigation.
Forms
(n) When electronic forms are designed to be completed online,
the form shall allow people using assistive technology to
access the information, field elements, and functionality
required for completion and submission of the form, including
all directions and cues.
Applets and Scripts When pages utilize scripting languages to display content,
or to create interface elements, the information provided
by the script shall be identified with the functional text
that can be read by assistive technology. When a web page requires that an applet, plug-in or other
application be present on the client system to interpret page
content, the page must provide a link to a plug-in or applet
that complies with sections (a) through (l) of the technical
standards for software applications and operating systems.
Multimedia Equivalent alternatives for any multimedia presentation
shall be synchronized with the presentation.
All else fails A text-only page, with equivalent information or functionality,
shall be provided to make a web site comply with the provisions
of this part, when compliance cannot be accomplished in any
other way. The content of the text-only page shall be updated
whenever the primary page changes.
