Accessibility Guidelines

The Web Accessibility Initiative of the W3C has an official document involving 14 guidelines that Web developers are encouraged to follow. I've provided a taste of the guidelines here.

  • Provide equivalent alternatives to auditory and visual content— If you're using sound or graphics, include text descriptions and employ HTML-based aids, such as the alt attribute in images, wherever possible.

  • Ensure that text and graphics are understandable when viewed without color— Many people are color-blind, and many people can't use visual displays with which to see color. Also, contrast is an imperative for all people, even those without vision problems.

  • Use markup and style sheets properly— This guideline is an important one! It encourages the creation of well-formed documents in accordance with the standards. Of course, you may make decisions that go against the grain, but if you do so, I encourage you to at least do so with awareness.

  • Provide clear navigation mechanisms— Clear and consistent navigation is not only an imperative in accessibility, it's an imperative in user interface design. Links should be clearly identified and organized, and graphical options should have appropriate alternatives available.
