Notice: an exception from this rule is valid in closed environments, where only specific browsers or screen readers are available. We have had good experiences with taking the following pragmatic approach, namely aiming at the most widely used combinations (newest stable versions): Mobile screen readers It is impossible to develop and test for dozens of possible combinations of browsers and screen readers.
Adding screen readers to the mixture does not make things easier: a long list of screen readers can potentially be combined with another long list of browsers, each combination possibly having its own characteristics. Diverging requirements in closed environmentsĪs web developers, we're aware of how hard it is to support all relevant devices, operating systems, and browsers.Other requirements may only apply in closed environments that are only open to a specific, deterministic group of users.
