Implement the aria-virtualcontent attribute. This attribute will allow web developers to signal to assistive technologies (ATs) that more content will be revealed if the user scrolls the page.


The purpose of aria-virtualcontent is to enable screen readers to experiment with solutions to make virtualized content accessible. Without this, an "infinite feed" - such as Twitter's that loads more new content every time the user scrolls to the bottom of the page - is poorly accessible. The content loaded once we reach the bottom of the page - called virtualized content - remains mostly inaccessible for assistive technology users. Web developers currently don't have a clear way to avoid this problem - thus this proposal.
