Accessible Design

The Web Content Accessibility Guidelines (WCAG) provide an international set of guidelines. They are developed by the Worldwide Web Consortium (W3C), the governing body of the web. These guidelines are the basis of most web accessibility law in the world. Version 2.0 of these guidelines, published in December 2008, are based on four principles:

  • Perceivable: Available to the senses (vision and hearing primarily) either through the browser or through assistive technologies (e.g. screen readers, screen enlargers, etc.)
     
  • Operable: Users can interact with all controls and interactive elements using either the mouse, keyboard, or an assistive device.
     
  • Understandable: Content is clear and limits confusion and ambiguity.
     
  • Robust: A wide range of technologies (including old and new user agents and assistive technologies) can access the content.

Guidelines

Provide appropriate alternative text

Alternative text provides a textual alternative to non-text content in web pages. It is especially helpful for people who are blind and rely on a screen reader to have the content of the website read to them.

Provide appropriate document structure

Headings, lists, and other structural elements provide meaning and structure to web pages. They can also facilitate keyboard navigation within the page.

Ensure links make sense out of context

Every link should make sense if the link text is read by itself. Screen reader users may choose to read only the links on a web page. Certain phrases like "click here" and "more" must be avoided.

Caption and/or provide transcripts for media

Videos and live audio must have captions and a transcript. With archived audio, a transcription may be sufficient.
