Focus Order

The sequence in which interactive elements receive keyboard focus when a user presses the Tab key or uses other keyboard navigation. In accessibility, a logical focus order that follows the visual and semantic structure of the page is essential for screen reader users and keyboard-only users to navigate efficiently. Calendar applications frequently have focus order problems where tabbing does not follow logical sequence through calendar elements, jumps unexpectedly between dates, or skips important controls. Proper focus order requires that focusable elements appear in a meaningful sequence in the DOM, that dynamically added content receives appropriate focus, and that modal dialogs properly contain focus within themselves.
