WCAG 2.4.3: Focus Order
WCAG 2.4.3 requires that if a web page can be navigated sequentially and the navigation sequences affect meaning or operation, focusable components must receive focus in an order that preserves meaning and operability. This criterion is essential for keyboard and assistive technology users who rely on a logical, predictable focus sequence to understand and interact with content.
