What is accessibility?

In the world of the web, accessibility means providing a broad audience the opportunity to “view” your web site, regardless of their disability. Accessible web sites are needed to accommodate people with disabilities such as no-to-low vision, color blindness, and limited mobility. These web sites can be used with assistive technology – screen readers, Braille tactile feedback devices, embossing printers, and TDD.

Who needs accessible web sites?

There are two main groups whose web sites should be accessible. The first is all state and federal agencies as they are required by law to accommodate those with special needs. The second is any organization or company that wants to reach a broader audience and wants the additional benefits of meeting web accessibility standards.

How is accessibility regulated?

The requirements for State of Kansas agencies are described in the Web Content Accessibility Guidelines for the State of Kansas Version 2.0. The federal requirements for all federal and state agencies are covered by Section 508 of the Rehabilitation Act. These guidelines are based on valid CSS2+ with either HTML4.0+ or XHTML 1.0+ code, which are collectively known as web standards. Both federal and state guidelines are very similar in their requirements and suggestions.

How to create an accessible web site?

There are two keys to creating and maintaining an accessible website. The first key is valid and appropriate use of web standards. Web pages should be tested for errors by the World Wide Web Consortium’s on-line validator, which identifies any incorrect use of web standards within the page.

Being able to validate a document’s semantic structure is only part of what is needed to create an accessible web site. The second key is to craft pages with accessibility in mind. Documents should be able to gracefully degrade to web browsers that do not have the ability to read the document in its intended format. For a video interview on your site, for example, a transcript of that interview should be available to a person who cannot hear. Additionally, pages should not rely on visual elements alone for tasks such as navigation, nor should they be worded in a confusing manner.

What are the benefits of web standards and accessibility?

Reduced Bandwidth

In general, a web page that uses web standards is 25-50% smaller in file size than a traditional web page because the page uses less markup and is separated from the look and feel of the site. The practical benefits of this are faster download time for your users and lower costs for your hosting service.

Easier Maintenance

The benefit of having smaller documents is also apparent in maintenance. Since most of the traditional HTML is replaced with web standard HTML, site developers and maintainers can concentrate on what is most important: the content of the page.

More Access

CSS2+ allows users to be able to access your site with more devices. One of the mainstays of CSS is the ability to apply a different style sheet to a document to change both its appearance and its user interface. Different style sheets can be used to enable a PDA, a voice reader, a Braille display, or other devices to access your site. High-contrast, large-print, and printable versions of your site can also be created.

Happier Federal Government

As noted earlier, the government requires that any federal agency must meet Section 508 guidelines of the Rehabilitation Act. For more information, visit www.section508.gov.

Better Search Engine Indexing

Search engines can use up to 100 different criteria for ranking your sites within their search results. Web standards allow you to place the content of your document near the top of the document source. This allows search engines to index the page’s content before processing the navigation and other repetitive elements. Some search engines scan only the top of web documents.

TDD (aka TTY)– Telecommunications Device for the Deaf. When a deaf customer calls, this device relays the through an operator. The operator then types what you say. That is then transmitted back to the caller’s TDD. The TDD then “displays” what you said. TDD devices are included in the CSS specification and can be used to enhance a sites accessibility.
