Issue: CSS Highlights Not Clearly Documented in AAM #550

Open HaTheo opened 6 months ago

HaTheo commented 6 months ago

The CSS custom highlight feature, introduced through the ::highlight() pseudo-element, provides a mechanism for styling text ranges on a webpage without impacting the DOM, and it's growing in usage in rich text web application. However, despite its benefits and the work done by the CSS team to get Accessibility API support, it is not explicitly documented within the Accessibility API Mappings. As such developers looking at this functionality are not aware of its support and there are not clear indications of how it should map across platform accessibility API's.
