Accessibility to everyone, regardless of browser, platform, operating system, plug-in or disability is probably the most important factor to consider when designing a web site. You should endeavour not to shut any web user out, anyone is a potential visitor and/or customer. Having an accessible web site, makes using your web site that much easier for everyone. Ease of use = return visitors.

"The power of the Web is in its universality. Access by everyone regardless of disability is an essential aspect."
-- Tim Berners-Lee, W3C Director and inventor of the World Wide Web

  • Make sure your site is usable on the main browser flavors and versions
  • Make sure it's usable without having to download a plug-in first
  • Test your site at the development stage to check it works on various operating systems with different browser flavors/versions
  • Use style sheets to separate style and content
  • Use the appropriate html tags to define your text - enables the text readers blind people use to read the text on your site
    • Make good use of headings, <em> and <strong>
    • Always specify alternative text for graphics - <img src="image.gif" width="10" height="10" alt="image description">
  • Check the colors you use aren't bad for those with various forms of color blindness
    • If in doubt - desaturate (make black and white) the design to see if it still makes sense
    • Don't use color as the only indicator of change (e.g. in a new section)
    • Always underline links
