| Accessibility... The Basics
An accessible website is one that allows as many people as
possible to access the infomation contained within it. An
inportant subset of accessibility is allowing people with
visual, aural, or physical disabilities full access to the
information and services available in the same way as
able-bodied people. Ensuring that your website is not dependant
on particular hardware or software is also an important
consideration when building accessible websites.
Is it worth it?
At least 10% of the population in most countries has
disabilities; visual, auditory, physical, speech, cognitive, and
neurological disabilities can all affect access to the Web.
Average age of population in many countries is increasing;
aging sometimes results in combinations of accessibility issues;
vision & hearing changes, changes in dexterity & memory.
Many elderly and disabled people rely increasingly on the
internet to obtain their goods and services. Few
organizations can afford to deliberately miss this market
sector. On top of this, accessible web design contributes to
advantages for able-bodies users too. Accessible websites:
Allow access to users of mobile phones, small display
scress, Web-TV and web-kiosks and other new web=enabled devices.
Increases usability in low bandwidth or slow connection
situations. Provide access across a wider range of computer
hardware and software. Other extremely important benefits
that make accessible websites worthwhile are that:
Many governments now require certain websites to conform to
accessibility guidellines. Accessible websites are easier to
index by search engines and therefore help drive traffic to your
site.
What does it entail? Many techniques involved in making
your website accessible will have no effect whatsoever on the
final look and feel of your site for the majority of users. It
will however allow users with disabilities to use assitive
devices such as screen readers (to read text out aloud to them)
and assistive input devices (for people with physical
disabilities) to access and use your site. Some of the key
concepts are: To provide textual alternatives for all
images and animations To ensure that textual content can be
resized to the users peronsal preference To ensure
sufficient contrast between text colour and background colour
To ensure that hyperlinks contain text that describes their
purpose. To ensure that hyperlinks are large enough to make
them easy to select To use a consistent and easy to navigate
layout
Other benefits The robots that search engines use to
catalogue your website are essentially 'blind' visitors to your
site. Accessible websites are therefore more search engine
friendly and result in better search engine rankings and
ultimately more visitors to your site. Other advantages include:
Better structure means easier and cheaper site
maintenance Accessible sites demonstrate that your
organiation takes its social responsibilty seriously
Increased support for internationalisation Reduces
hosting costs I believe accessibility is beneficial for
all involved and should be a consideration of every website.
