Why should the tab order be preserved via the Focus Order principle?

• A. Tab order is primarily cosmetic.
• B. Maintaining tab order helps preserve meaning and operability.
• C. After focus, the page context is reset.
• D. Tab order has no impact on accessibility.

Answer: (B)

Focus order determines the sequence keyboard users move through interactive elements. Preserving it ensures that the flow of focus matches how the content is read and how tasks should be performed. When tab order aligns with the visual grouping and reading order, it keeps meaning intact and allows users to navigate and operate controls predictably. If the order is shuffled, keyboard users can land on controls out of context, miss related fields, or perform actions unintentionally, making the page harder or impossible to use. So, maintaining a logical tab sequence is essential for both understanding content and being able to interact with it effectively. The other statements miss the point: tab order isn’t cosmetic, it doesn’t inherently reset page context, and it does have a real impact on accessibility.
