Ensure pages are functional when programmatic objects are turned off or not supported. Use application-level triggers rather than user interaction-level event triggers. If device-dependent attributes must be used, provide redundant input mechanisms (i.e. specify two handlers for the same element). As a last resort, provide equivalent information on an alternative page.
