Web Content Accessibility Guidelines
¨
¨Guideline 6
¨Ensure that pages featuring new technologies transform gracefully.
¨
¨Ensure that pages are accessible even when newer technologies are not supported or are turned off.
Although content developers are encouraged to use new technologies that solve problems raised by existing technologies, they should know how to make their pages still work with older browsers and people who choose to turn off features. Disabling java for security reasons is a good example.
