Building websites that EVERYONE can use...
In this slideshow presentation, I will examine and discuss the fast
growing Website Accessibility movement and why it should be a crucial element to your everyday development.
First, I will cover what website accessibility is; including
definitions, history, involved organizations, and Canadian/U.S guidelines. Then, I will
supply an overview to some generalized website accessibility trends and practices. Next, I
will showcase some tools that help with making a website more accessible. From there, I
will talk about WordPress Accessibility, more specifically the WordPress Accessibility
Group and what they do as well as how they are making a difference. Finally, I will
showcase some WordPress plugins that can be used to make your WordPress website more

3. What is Web Accessibility?
According to the W3C Web Accessibility Initiative...
http://www.w3.org/WAI/intro/accessibility.php
The W3C launched the Web Accessibility Initiative in 1997 with endorsement by The White House and
W3C members. It has several working groups and interest groups that work on guidelines, technical
reports, educational materials and other documents that relate to the several different components of
web accessibility. These components include web content, web browsers, media players, authoring
tools, and evaluation tools.
Millions of people have disabilities that affect their use of the Web. Currently most Web sites and Web
software have accessibility barriers that make it difficult or impossible for many people with disabilities
to use the Web. Web accessibility encompasses all disabilities that affect access to the Web, including
visual, auditory, physical, speech, cognitive, and neurological disabilities.
Web accessibility means that people with disabilities can use the Web. More specifically, Web
accessibility means that people with disabilities can perceive, understand, navigate, and interact with
the Web, and that they can contribute to the Web.
One of the roles of the Web Accessibility Initiative (WAI) is to develop guidelines and techniques that
describe accessibility solutions for Web software and Web developers. These WAI guidelines are
considered the international standard for Web accessibility.

10. WordPress Accessibility Tools
There is a long list of useful WordPress tools that can help any developer optimize a website for
total accessibility.
Here is a list of the some I have used in projects:
WP Accessibility - http://wordpress.org/plugins/wp-accessibility/
This plug-in helps correct a variety of common accessibility problems in WordPress themes.
While most accessibility issues can't be addressed without directly changing your theme,
WP Accessibility adds a number of helpful accessibility features with the minimum amount
of setup or expert knowledge.
Zoom - http://wordpress.org/plugins/zoom-widget/
Zoom is a small smart solution for improving your web site attractiveness. WordPress Zoom
plugin enables site users to resize the predefined areas of the web site.
Font-resizer - http://wordpress.org/plugins/font-resizer/
This plugin allows you to give the visitors of your site the option to change the font size. The
plugin acts over jQuery and saves the settings in a cookie. So the visitor see the same font
size if they revisit your site.
