WAI: Strategies, guidelines, resources to make the Web accessible to people with disabilities
The table below lists uses for a technology along with results for all of the operating system, browser and assistive technology combinations chosen on the previous page. Each cell contains an icon representing whether test results indicate that the use is supported (+), not supported, (-) or partially supported (/). Where cells contain a single icon indicating the result, all testers reached the same conclusion about the support for that use. If different testers reported different results, multiple icons will appear in that cell indicating which results were reported and additional investigation will be carried out to determine if there is a test error or to document the conditions which led to different results. Empty cells indicate that no test data for the use have been gathered.
