ARIA Live Region

An ARIA live region is a section of a web page marked with the aria-live attribute that announces dynamic content changes to assistive technologies without requiring user focus to move to the updated area. Live regions are essential for making real-time updates — such as status messages, search results, chat messages, or error notifications — accessible to screen reader users who would otherwise be unaware of visual changes occurring elsewhere on the page. The aria-live attribute accepts values of "polite" (waits for the user to finish current activity), "assertive" (interrupts immediately), or "off" (disables announcements).
