A
well designed website makes information accessible. However,
web designers must be aware of accessibility issues in order
to accommodate people with disabilities. Individuals with
disabilities use the Internet for the same reason as others
-- research, banking, shopping, job search or education. In
an effort to address the needs of all users, the U.S. House
of Representatives has adopted guidelines for congressional
offices to strive to meet the needs of all constituents, including
those with disabilities. ADA compliance is strongly encouraged
and considered to be "good practice" for website
design.
ADA compliance
includes standards based on Federal
Section 508 of the Rehabilitation Act of 1998 and World
Wide Web Consortium accessibility guidelines.
At a minimal,
the following associated problems and corrective actions should
be taken to meet a Level A conformance:
- provide
for all images, including image maps, text alternatives
(ALT tags). When a viewer's mouse is placed over an image
a text description of that image appears
- scripts
such as scrolling text messages, should not be used to impart
information
- fonts
smaller than point size 10 (or font size="-1")
should not be used
- flickering,
blinking or flashing designs can cause seizures in people
with certain neurological disorders and should not be used
- framed
web pages should be titled
- data
tables should use titles on all rows and columns
- the
use of tables to layout or design a page should be kept
to a minimum
- good
color contract should be maintained
- web
page design should be uncluttered
- navigation
should be easily understood
