What does focus management ensure on a web page?

Focus management is crucial for ensuring proper navigation for users, particularly those relying on keyboard navigation or assistive technologies such as screen readers. When a user navigates a web page, it is important that the focus—the visible indicator of where the user is on the screen—moves logically through interactive elements like links, buttons, and form fields. This logical movement allows users to predict where they will go when they use keyboard commands, enhancing their experience and reducing cognitive load.

Effective focus management also includes managing how focus is set when portions of a page are dynamically updated or when modal dialogs appear, ensuring that the user's focus shifts appropriately to these changes. This intentional handling of focus supports accessibility, enabling all users, including those with disabilities, to navigate the web smoothly and efficiently.

Other aspects mentioned in the choices—like effective use of images, consistent layout design, and fast loading times—are important for a well-rounded web experience, but they do not directly relate to the concept of focus management in navigation.
