An Idiot’s Guide To Accessible Website Design

If you are designing web sites in the UK, you probably already know that the Disability Discrimination Act (DDA) mandates web sites be accessible by visually and physically disabled persons. But even if you work in a locale that doesn’t have any accessibility requirements yet, web designers have an obligation to make their clients’ web sites available and accessible to anyone who wishes to visit.

Why? According to a report by the Danish Center for Accessibility, as many as 25% of the world’s Internet users have some sort of visual, auditory or mobility disability.

Fail to take into the consideration the needs of these people and you are depriving your client the opportunity to connect with a huge audience. Not only doesn’t that make good business sense, but also you could end up breaking the law. For example, if you’re working for an organization that is hoping to do business with the U.S. government, you’re going to run up against the “508 Act”.

This regulation requires all Federal agencies that “develop, procure, maintain, or use electronic and information technology”, to provide access to disabled users that is comparable to access available to everyone else.

How To Meet Accessibility Requirements

In order to provide for the access needs of the disabled, it’s important to understand the technology challenges these users face everyday.

  • Use of non-standard browsers, earlier versions of mainstream browsers, or specially designed text-to-speech and text-to-brail readers that do not function in the way we normally understand browsers to function.
  • Lower screen resolutions, the need for larger fonts, and reduced screen size.
  • Colorblind users who cannot easily “Click the red button to cancel your order.”
  • Users with motor impairment may use non-standard pointing devices and keywords.

Fortunately, The Guesswork Has Been Eliminated

The World Wide Web Consortium (W3C) maintains accessibility standards and best practices on their All Standards and Drafts page; of particular interest are the Web Content Accessibility Guidelines (WCAG) 2.0.

Is Accessibility Design In Your Future?

It should be, if it isn’t already. In addition to the UK’s legal requirements, many other countries and local governments are becoming more involved in ensuring equal Internet access to everyone regardless of physical disabilities.
