Introduction
It is the goal of the National World
War II Museum to create and maintain web sites that are accessible
to all citizens visiting our website. All web development must
comply with priority level 1 of the Web
Accessibility Initiative's Web Content Accessibility Guidelines.
Web Site Design Standards
The following standards were taken
from the Access Board Section 508 Guidelines, and can be found
on the Access
Board's Section 508 Web Site. The guidelines were developed
by the Access Board as outlined by the amended Rehabilitation
Act of 1998.
§ 1194.22Web-based intranet
and internet information and applications.
(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.
Site Validation
Both
automated tools and human review are used to validate the accessibility
of the National World War II Museum web site.
