Screen reader reliability HTML, CSS and ARIA
Overall reliability of HTML, CSS and ARIA features designed for assistive technology in different screen reader / browser combinations.
The graph only includes results for tests which are expected to work. Expected failures (e.g. missing ALT on an IMG) are not included in the graph.
The solid area in the graph shows percentage of tests that pass in all tested interaction modes. The cross hatched area shows partial passes that only work in some interaction modes.
An example of a partial pass is when form labels are read when tabbing, but ignored in browse mode.
