Answer:The pseudo-class selector for links does not let you use CSS to change the formatting for the :visited pseudo-class. This pseudo-class represents links that have been visited by the user, and it is not possible to style them using CSS. This is for security reasons, as allowing styles to be applied to visited links could potentially allow attackers to track the browsing history of users.
The other pseudo-class selectors for links, such as :hover, :active, and :focus, can be used with CSS to change the formatting of links in different states. These pseudo-classes represent the different ways in which users can interact with links, such as by hovering over them with a mouse, clicking on them, or tabbing to them with the keyboard. Using these pseudo-class selectors, you can apply different styles to links depending on how they are being used, allowing you to create more interactive and engaging user interfaces.
