WCAG 1.0 Priority 2
WCAG WCAG Guideline 7. Ensure user control of time-sensitive content changes.
Providing updated information to users is an important part of interacting with web site and web applications and one mechanism to do this is to refresh the page that the user is currently viewing. Users need to be aware that the page is being refresh otherwise they may not know that something has changed. Similarly, assistive technologies need to be made aware that content on the page has changed in order to re-present it to the user.
- View the pages in a web browser and test any functionality to ensure that refreshing content is made aware to the user.
