Guidelines for Creating an Accessible Web Site
(a) A
text equivalent for every non-text element shall be
provided (e.g., via "alt", "longdesc", or in element
content).
(b)
Equivalent alternatives for any
multimedia presentation shall be synchronized with
the presentation.
(c) Web
pages shall be designed so that all information conveyed
with color is also available without
color, for example from context or markup.
(d)
Documents shall be organized so they are readable without
requiring an associated
style sheet.
(e)
Redundant text links shall be provided for each active
region of a
server-side image map.
(f)
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.
(g)
Row and column headers shall be identified for data
tables.
(h)
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.
(i)
Frames shall be titled with text that facilitates
frame identification and navigation.
(j)
Pages shall be designed to
avoid causing the screen to flicker with a frequency
greater than 2 Hz and lower than 55 Hz.
(k) 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.
(l) When
pages utilize
scripting languages to display content, or to create
interface elements, the information provided by the script
shall be identified with functional text that can be read by
assistive technology.
(m) 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 §1194.21(a) through (l).
(n) When
electronic forms are designed to be completed
on-line, 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.
(o) A
method shall be provided that permits users to
skip repetitive navigation links.
(p) When
a
timed response is required, the user shall be
alerted and given sufficient time to indicate more time is
required.
